Writing on the social networking site this morning (January 24), the 'Nobody's Perfect' songstress explained that it's important to remember we all make mistakes, but we need to be aware of them so that we can learn life's lessons:

"Do good. Inspire. Set an example to yourself and others. Have faith. Make your actions loud. Have fun. Be nice. Love strong."

She added: "We all make mistakes. Its human. Just learn from them. Repeating them and being aware of it is the dangerous bit."

When asked by one of her fans how she is spending her day, Jessie J replied: "Styling for the voice, meetings and studio :)"

Earlier this month, she confirmed plans to shave her head for charity and revealed that the event will take place on March 15 for Comic Relief.

The boyband are among many celebrities who have appeared in a video to promote Enough Food for Everyone IF.

The likes of actor Orlando Bloom and Bill Gates also feature in the short clip, which aims to raise awareness of the charity project.

One Directon's Harry Styles says in the video: "One third of children in sub Saharan Africa are malnourished."

Bandmate Zayn Malik adds: "Big corporations avoid paying millions to Africa every day. If we stop this, all of Africa could have enough food to eat."

The project sees a host of well known charities such as UNICEF and Oxfam come together to promote the idea that governments can unite in an effort to tackle world hunger.

The musician and Hollywood actor will perform in New Orleans on February 2 for the DIRECTV Super Saturday Night charity event.

This Super Bowl weekend extravaganza will be hosted by Mark Cuban and has been confirmed to take place at the DTV SuperFan stadium.

Proceeds from ticket sales will be donated to Shriners Hospitals for Children and the Super Bowl will then take place the following day, February 3, with a live half-time performance from vocal sensation Beyoncé.

Timberlake's last solo tour, the 'FutureSex/LoveShow', took place in 2007 although he played an impromptu set midway through a FreeSol concert two years ago.

Listen to 'Suit & Tie' below:

The singer will travel 68 miles down the Zambezi river in Africa to raise money for Red Nose Day, which is taking place on March 15.

She will be joined by actress Chelsee Healey, comedian Jack Dee, Dara O Briain and DJ Greg James as the group of celebrities endure wild animals and unpredictable water.

Speaking about the trip, the Spice Girls star said:

"It's going to be tough. It's going to be physically and emotionally demanding, but we've all got each other and hopefully we'll be able to get through it."

The BT Red Nose Challenge: Hell And High Water trip is expected to raise a massive £1 million.

She was recently photographed for Le Figaro madame magazine and in the accompanying interview, Del Rey explained that while she loves music she wants to focus her attention on helping those in need:

"Music was my passion, but my work with this foundation is more important. I myself had the chance to be [helped by an establishment]. Helping others now feels like it's my turn to give something back. I want to become a sort of Angelina Jolie."

"Like her, I think fame is nothing in itself, but it can be put to good use - by using it to generate money for charity for example."

She also opened up about how she began drinking when she just 14 and added: "When you no longer drink, it is more difficult to celebrate. In fact, when I quit drinking, I lost my life. It took my all to reinvent myself. Find the roots. It was very difficult. At the same time, I had never felt rooted in whatever I've done or wherever I've been since."

The singer announced the idea of the fundraising project many months ago, but it has now been confirmed that she will shed her hair on March 15 for Comic Relief.

People are invited to sponsor the singer as she prepares to undergo the eye-catching hair cut, whilst fans are also encouraged to undertake their own hair related fundraising initiative, such as dying it red.

Comic Relief is an annual fundraising event, with One Direction for example recently heading to Ghana to visit local children and film a segment.

The event's website says that a £5 donation could pay for a vaccine against a number of deadly diseases for a child in Malawi.

An artist's representation of what Jessie J could like post-shave can be seen below.

The boys have teamed up with #onepiece2work, a charity initiative run in conjunction with the CAW Foundation and onesie company OnePiece.

They are auctioning off a green onesie that was personally hand-printed by the members of One Direction.

At the time of writing, the auction stands at $1,525.00 with just over a week left to run.

If that isn't quite your thing, the 'What Makes You Beautiful' stars have teamed up with OnePiece for a onesie with printed hand-paint motifs courtesy of the five band members, whilst there are also personalised garments with a hand-print from each singer.

Speaking to We Love Pop magazine, King explained that she had to paid excess baggage fares for the five suitcases of clothes she took to the U.S., but it was worthwhile because she felt compelled to help in any way she could:

"Everyone took about three or four cases and I took five. I got a huge fine. I gave everything I didn't wear to the Hurricane Sandy appeal in New York, which meant I could fill the empty cases with new stuff on my return! Everyone wins!"

Earlier this month, The Saturdays announced that they will release their debut American EP, entitled 'Chasing The Saturdays', on January 29. The girls' television series of the same name is also due to begin on January 20.

The trending topic '#cutforBieber' made its way around the social networking site and encouraged fans to self-harm in an attempt to get the 'Boyfriend' singer to change his supposed bad boy ways.

Now, a British charity for youth mental health named YoungMinds has issued a statement on how dangerous a suggestion like this can be, especially on the internet where nothing is moderated and the audience can be easily influenced:

"Self harming is not a fashion, fad or statement. It's a signal that young people are experiencing extreme distress and need help. Cutting is a self-destructive act that is a way of coping with overwhelming emotions."

"To suggest young people cut themselves as some kind of protest is a very perverted and dangerous idea, and these people need to take responsibility and stop this activity immediately."

Watch Bieber perform a stunning version of 'As Long As You Love Me' here:

The beauty has been named the face of the Rock Up In Red campaign, which will take place next month, and she has been pictured in a stunning outfit to support and promote the worthy cause.

Speaking about her involvement, King explained:  "If there is one thing you must do to show your support rock up in red on the first of February I really hope everyone will be joining me in the fight against heart disease. Anything goes as long as it’s red."

Last year, she confessed that the charity is especially significant to her because her grandfather passed away after suffering a heart attack when she was younger.

She is calling for fans to donate £2 to Rock Up In Red and help the fight against heart disease on February 1, 2013.
