At least 24 people have died in the wake of the natural disaster, which flattened communities of Underwood's home state.

The former American Idol winner said that she will fund the donation with money made from her live shows. The country star said:

"I have watched the devastation in my home state of Oklahoma over the past several days with great sadness."

Underwood continued: "With the help of my fans who attended my concerts over the past year, we can offer the Red Cross a little extra help in comforting those affected by the recent tornados."

Red Cross chief development officer Neal Litvack added:

"The impact of the tornados in Oklahoma and the Midwest was devastating and the road to recovery will be long for many families. Through the generosity of Carrie, the American Red Cross can quickly respond with shelter, food and comfort now, and with lasting help as they move toward recovery."

The Detroit Free Press reports that a 12-page complaint has been issued against the social networking company for their use of the 2000 track 'Under The Influence'.

Eight Mile Style claim that Facebook didn't ask for permission to use the song on the advert, which was broadcast during a Mark Zuckerberg webchat on April 4.

The lawsuit says that a new version of the advert featuring different music was uploaded online days after in order to replace the original clip - "an admission that Facebook knew it had infringed", the publishers say.

As previously reported, Eminem was recently pictured in the studio alongside fellow rappers Royce Da 5'9" and Big Sean.

His last album meanwhile came in the shape of 2010's 'Recovery'.

During an interview with Access Hollywood, the 'Can't Be Tamed' beauty explained that she's so excited to release the track to the public:

"I really made a record kind of before I had a label, before I had anyone that was really telling me what it needed to be. It's just really about experimenting. 'We Can't Stop'... sets up what I'm trying to say. But it's just a message for my fans. It's a song that's for the fans."

The track is due to be released in 12 days (June 3) and there is currently an online countdown ticking away on Cyrus's official website so that followers can keep an eye on when it will drop.

She recently attended the 2013 Billboard Music Awards and shared a snapshot of herself posing with fans on the red carpet before the show via her Twitter page (shown below) and accompanied the picture with the caption: "Best part of last night ❤ #smilers #wecantstop"

Member Howie Dorough told MTV News that to see a new group paying homage to an act as established as themselves was great as it's important to acknowledge music's history:

"I think they did a good job on it. One of the writers, that's written almost all their big stuff, Rami Yacoub, he worked with us in the early days with Max Martin and stuff like that, some of the biggest songs of ours. The sound that they've originated was definitely not too far from where it came, from the same Swedish camp."

"It's nice to see groups like that pay homage to us. We definitely paid homage to groups in the earlier days that we admired like Boyz II Men, Color Me Badd, Shai, New Edition." Dorough added: "So it's cool. I think they did a great job. It seemed like it went over really well."

Swift's hit 'Dear John', which includes lyrics such as "Dear John, I see it all. Now it was wrong, don't you think 19 is too young to be played by your dark twisted games, when I loved you so?", is reportedly about her short-lived romance with the superstar and he told Rolling Stone magazine that it humiliated him:

"It made me feel terrible. Because I didn't deserve it. I'm pretty good at taking accountability now, and I never did anything to deserve that. It was a really lousy thing for her to do."

"I never got an e-mail. I never got a phone call. I was really caught off-guard, and it really humiliated me at a time when I'd already been dressed down. I mean, how would you feel if, at the lowest you've ever been, someone kicked you even lower?"

Mayer also explained that from a songwriting perspective, he doesn't like the track at all: "I will say as a songwriter that I think it's kind of cheap songwriting."

"I know she's the biggest thing in the world, and I'm not trying to sink anybody's ship, but I think it's abusing your talent to rub your hands together and go, 'Wait till he gets a load of this!' That's bullshit."

The 'Gravity' sensation, who was forced to pull out of his full north American tour back in March after a granuloma had grown back from where it had previously been removed, has shot to the top of the U.S. albums chart with 'Born and Raised'. 

The record sold over 219,000 copies in its first week according to Nielsen SoundScan.

He posted a message to his fans via his official Tumblr page on May 25 and thanked them for supporting the record because he has been unable to promote it with live shows, and explained that the projected sales figures were "incredible on all your parts because there has been very little I've been able to do to promote it."

He also opened up recently about the controversial interviews he gave back in 2010 and told Guy Raz's radio show 'All Things Considered':

"I wasn't prepared to be honest, but I knew that I had to be open. When you're just open but not honest, then you start free-associating garbage. It doesn't mean I can go back and scrub it out, but I understand it [now]."

Back in 2010, Mayer frequently made headlines by giving reporters revealing quotes and candid details of his relationships with Jennifer Aniston and Jessica Simpson. Earlier this week, two years later, he sat down with Ellen DeGeneres and spoke about his need to shy away from the press for a while:

"For a couple of years, it was just figuring it all out, and I'm glad I actually stayed out of the spotlight. Because I think back then I would've said, 'Give me two weeks or let me get out and do Ellen and let me explain myself.'

"It was like, 'No, idiot. Go away and be 33 and 34 instead of 28 for the fourth year. The plan that originally gets you out of high school and your hometown, in front of people... that plan was over. I had done it. I just sort of lost my head for a little while." 

He also talked about the returning granuloma on his vocal cords that forced him to cancel his entire U.S. tour recently, adding:

"They cut this thing out of your throat and then they inject your vocal cords with Botox, which freezes your vocal cords so that this thing can heal without smacking up against the other side. I just need more Botox next time."

"Shadow Days" is the first single from John Mayer's forthcoming album Born and Raised, which will be released May 22 on Columbia Records.  Early reaction toBorn and Raised has been extremely positive, with Rolling Stone giving the album 4 stars as the lead review in their latest issue and calling it "some of the most convincing music of Mayer's career...every breezy solo or sun-dappled acoustic spindle is comfy and luxe like a spun-silk blanket."  Though Mayer was forced to take an indefinite hiatus from live performing due to the return of the granuloma in his throat, he will be making the rounds on TV to talk about the new album leading up to the release.  He will appear on The Ellen DeGeneres Show on May 15, The Late Show With David Letterman on May 17, and on Late Night with Jimmy Fallon on release day, May 22. 

Mayer produced Born and Raised with Don Was, who worked on albums for acts such as the Rolling Stones, B.B. King and Bonnie Raitt. Rock legends David Crosby and Graham Nash provide vocals on the title song and musicians joining Mayer on the album include highly-regarded keyboardist/pianist Chuck Leavell—who has worked with the Rolling Stones, Eric Clapton and The Allman Brothers Band—as well as previous collaborators Sean Hurley on bass and Aaron Sterling on drums.  Jim Keltner makes a special appearance on drums on "Something Like Oliva."

Mayer's previous albums—Room for Squares, Heavier Things, Continuum and Battle Studies—have sold more than 12 million copies combined.  He has been honored with seven Grammy Awards and an additional 11 nominations.  He has also been included in Time Magazine's annual Time 100 list of the most influential contemporary thinkers, leaders, artists and entertainers, and twice been featured on the cover of Rolling Stone Magazine's annual "Guitar" issue.

The vocal sensation revealed to his fans back in March that a recurring and serious throat condition forced him to scrap his entire US tour and added that he now has "no choice but to take an indefinite break from live performing".

Today (April 27) Mayer shared the video for 'Shadow Days', which will act as the lead single from his new album 'Born And Raised', and it shows him travelling across the Western frontier while singing the lyrics and playing his guitar.

Mayer also took to his official Facebook page earlier today and told his fans that they can unlock "exclusive photos taken by John and director Philip Andelman from the "Shadow Days" road trip" by clicking and sharing a certain link.
