The singer's bosom has come under the spotlight recently as some fans discussed its size after seeing the music star on her UK and Ireland tour.

Cole kicked off the arena tour in Belfast on Wednesday (October 3) before performing in Dublin the night after (October 4).

The revealing outfits used in her show prompted some fans to speculate on Twitter over the possibility that she has had her chest augmented.

A rep for Cole, however, said that definitely "has not" had breast implants.

The 'Call My Name' star is due to perform in Nottingham tomorrow night (October 6).

The singer is used to going on the road with her Girls Aloud bandmates but she is currently doing it alone to promote her 2012 album 'A Million Lights'.

Cole performed in Belfast last night (October 3) on the opening night of the tour and she is due to take to the stage in Dublin tonight (October 4).

Speaking to Capital FM, the Geordie said that whilst she isn't too worried about performing the shows, she is going to find it a bit weird without her bandmates. When asked if she was nervous, Cole said:

"I'm not. I'm a long time in the industry. It's nerve-wracking that I'm alone."

She continued: "The only thing I've done alone is when I supported the [Black Eyed] Peas, so obviously it's a far bigger scale. But I'm so excited, the choreography is sick."

Cole's arena tour is also set to hit cities such as Glasgow and London before concluding with two hometown shows in Newcastle.

She uploaded a photograph of herself holding up the book, entitled 'Cheryl - My Story', and tweeted out an accompanying message which simply read: "It's REALLY here !!!!"

The book will be available from October 11 and the 'Promise This' beauty recently admitted that certain people should be nervous about its contents because she wanted to tell the truth while writing it:

"I've actually got a lot of stuff to say and things to put straight and it's been a cathartic experience - more than I thought. [It's] draining - but really good to just get everything out and on to a piece of paper."

She also revealed that she ran the autobiography past her ex-husband Ashley Cole before it went to print.

The track, which features a cameo from British rapper Wretch 32, is the latest song to be lifted from her 2012 album 'A Million Lights'.

It follows songs such as 'Call My Name' and 'Under The Sun', which hit No.13 in the UK singles chart.

The lyric video for 'Screw You' compiles a host of fan-made content collated via Instagram.

Cheryl Cole meanwhile is due to head out on tour across the UK and Ireland in October on her first ever arena jaunt.

Wretch 32 had previously confirmed his involvement in the tour - although it wasn't clear if he would be an official support act.

Cole will begin her tour in Belfast on October 3 before finishing up in Newcastle for two dates on October 16 and 17.

Speaking to Zoo magazine, Marsh questioned why Cole continuously seems to get "hurt" by men and explained that it's probably because she's "so good and innocent", but could do with a tough makeover:

"I think that Cheryl Cole could do with a bit more of a bad girl side. She's so good and innocent that men just want to protect her, but she keeps on getting hurt."

"She needs to start calling the shots and be a bit stronger all round."

Meanwhile, Cole took to her official Twitter page and told her followers that she can't wait to kick off her new headlining tour next week:

"This time next week I will be soundchecking for the first night of my #AMillionLightsTour .. Who's ready ???"

The reality TV star, who is currently dating Kanye West, told Nuts magazine that she was bowled over with how pretty the former X-Factor judge is after spotting her at a gym.

"I think she's so beautiful. I saw her at the gym once with no make-up on and she was just as gorgeous, if not more, looking natural."

The 31-year-old, who recently admitted that she falls in love fast, also discussed the sex-tape with R&B star Ray-J that was leaked in 2007, insisting that she has no regrets about making it:

"I'm a stronger person because of everything bad that's happened to me. I was devastated but in life you're measured not by the mistakes you make but by how you overcome them.

"He was my boyfriend at the time, it was nothing scandalous."

The singer is releasing her first ever book on October 11 and it seems that she has quite a few things to say in it.

Speaking on ITV's This Morning yesterday (September 11), Cole said that spilling her thoughts and experiences on paper was a purifying thing to do. She said:

"I've actually got a lot of stuff to say and things to put straight and it's been a cathartic experience - more than I thought. [It's] draining - but really good to just get everything out and on to a piece of paper."

Cole was then asked whether anyone should be nervous about the book coming out, to which she replied: "Only if they think they should be! If they think they should be then they probably should."

It has been speculated that the autobiography will mention ex-husband Ashley Cole and former X Factor colleague Simon Cowell.

Walsh will be one of fourteen contestants on the popular dancing reality TV show, which begins on Saturday (September 15).

Talking to BBC Newsbeat, Cole said that she "can't wait" to watch Walsh dance on national TV. She said:

"I think it's amazing. I can't wait actually. I'm gonna go watch as much as I can."

However, the 'Call My Name' singer believes that Walsh's perfectionism could get the better of her as the series progresses. She said:

"She's really hard on herself that's the only thing I worry about. She is a perfectionist and if she doesn't feel like she's doing it perfectly she'll give herself a hard time. So I am going to have to rein that in."

Joining the Girls Aloud singer on the show are the likes of Westlife man Nicky Byrne and Daybreak presenter Richard Arnold.

News emerged over the weekend that the Girls Aloud star would be helping out Barlow during the judges' houses section of the series.

It prompted show supremo Simon Cowell to tweet: "Welcome back Cheryl. X."

However, the Metro quotes the 'Call My Name' singer as confirming that her shock return to the TV talent show wasn't for Cowell - but for her friend Barlow. She said:

"I saw Simon's tweet. I'm not doing this for him. I am doing this for Gary as he's my friend and he asked me to do it."

Speaking about recording Cole's cameo on the X Factor, Barlow had previously joked on Twitter: "Just so we don't clash, I'm wearing the pink suit with the red shoes ;)."

The Girls Aloud star, who releases her official life story on October 12, told ITV’s The Jonathan Ross Show, that she felt it was only fair she informed the Chelsea defender about what she’d written:

"Yes. I didn’t have to but I let him know it was happening. It wouldn’t have mattered if he did [ask for changes], to be quite honest, I just thought it would be nice that I gave him the heads up so he can leave the country two weeks before." 

The 29-year-old, who also joked that she’s never getting in a car with will.i.am ever again, went on to tell the talk show host that a Girls Aloud reunion is definitely on, adding:

"Very soon. It could be before Christmas."
