Rylan Clark-Neal’s celeb pals ‘rally round him’

This spiky-haired teen won X Factor waaaaay back in 2007, scoring a Christmas number one with a cover of Whitney Houston and Mariah Carey's When You Believe. And, while there's no denying that he was cute, the X Factor champion was definitely a bit too baby-faced for us to lust over properly. But, nowadays, he's looking VERY sexy indeed, after switching up everything from his hairstyle to his workout regime at the gym. He definitely looks good on it, doesn't he?

When Frankie Cocozza joined The X Factor back in 2011, he was a scruffy 18-year-old with birds nest hair and a LOT of eye makeup.

The X Factor star first burst into our lives as a sweet and fresh-faced teenager from Liverpool, starring as tormented child Anthony Murray in the Channel 4 soap opera, Brookside. When he was 18-years-old, he auditioned for The X Factor and survived right up until the show's final, where he lost out to Leona Lewis. Since then, we've seen him appear in Dancing On Ice and in several West End musicals - but, when he was dismissed from his record label in November 2007, he fell off the radar a little bit. Now he's back - and he's DEFINITELY become a fan of lifting weights, hasn't he? Read more about his transformation here.

Eoghan was just 16-year-old when he shot to fame in the ITV competition in 2008, and made it all the way to the final where he finished in third place.

Since then, Eoghan has turned his back on music – and instead has made a bit of a name for himself in Irish football. And he looks completely different, doesn't he?

X Factor's Christopher Maloney has shocked fans after revealing he spent £60,000 on cosmetic surgery following a nervous breakdown.

Remember when Chloe Mafia auditioned for The X Factor in 2010? Well, it seems like rejection from the show has done her no harm, as the Wakefield lass looks unrecognisable these days. In fact, Chloe - now known as Chloe Khan - is now a MILLIONAIRE and living a life of luxury overseas. She said: "My lifestyle is pretty incredible now – it's mansions and private jets and everything else that I could only imagine when I was younger." The money allowed her to completely reinvent herself with cosmetic surgery and designer clothes - and she's confessed to a boob job or two, as well as rhinoplasty.

The shy and retiring singer shot to fame, thanks to his modest nature and sweet-as-an-angel voice, back on The X Factor in 2012. He finished in second place, and has since gone on to find success as a singer; in fact, his second album (which features collaborations with the likes of Diane Warren) is currently in the works. But Nicole Scherzinger's protégé hasn't just been working on his music; he's also been working on his look, too. Think makeup and VERY well manicured eyebrows - we're jealous. To critics of his new look, he said simply: "Any judgement of beauty will always be an opinion." Read more about his transformation here.

One of the biggest X Factor success stories, Leigh-Anne Pinnock is now 1/4 of Little Mix - but she's just as prone to a makeover as her fellow former X Factor contestants.

John and Edward Grimes were the X Factor twins with BOUNDS of energy and gravity defying uairsylts.
