She's one of the standout acts on this year's series of the X Factor thanks to her glamorous Hollywood look and old school vocals.
But Chloe-Jasmine Whichello's squeaky clean reputation has come under threat due to allegations by her ex-boyfriend Dave Kai Piper, who claims she is prone to booze and cocaine benders.
The photographer told The Sun on Sunday that Chloe's 'addictive personality' ruined their three-year relationship, with the platinum blonde beauty's alleged all-day drinking and secret drug use driving a wedge between them.

However, a source close to the 23-year-old star claims Dave's remarks are unfounded and Chloe has been living a clean and healthy lifestyle.
The insider told MailOnline: 'Chloe and her family are very disappointed and hurt by Dave's claims, having supported him both financially and emotionally over many years during his friendship with Chloe.
'Chloe's modelling work has meant she has visited many interesting places but she chose to stop drinking socially a while ago of her own accord. She is now focused on her singing and doing well in the competition.'

Posh X-Factor wannabe Chloe-Jasmine wows the judges
In spite of the shocking claims, Chloe once again wowed the judges on Saturday night's episode of the ITV show.
The eccentric star - who appeared on Naomi Campbell's modelling search show The Face last year - had the audience in hysterics with her cut-glass accent and witty banter.
Asked by head judge Simon Cowell whether she had any pets, Chloe joked: 'No, but I had a boyfriend that behaved like one.'

She earned a standing ovation from the crowd with her flawless rendition of Why Don't You Do Right, the jazz tune best remembered from Who Framed Roger Rabbit.
Amidst ecstatic exclamations of 'Oh My Gosh!', the well-spoken model received high praise from the judges.
Louis Walsh enthused: 'I loved your audition, I love everything about you. I love your name, I love your style, I love the whole vibe.'
Cheryl Cole chimed in: 'There's something really fascinating and mesmerising about you.
'Today I could tell you were a bit more nervous, but you're elegant, graceful, you're like old school Hollywood glamour. I love you.'
And even notoriously tough to please Simon seems to have fallen under Chloe's spell.
He mused: 'I don't think you've yet connected with the right song and you are suffering from nerves. But I think you're interesting.
'We've never had anyone like you on the show before. Just in terms of the way you look, the way you sound.
'I always judge an audition by [thinking], can I remember you? And I'm definitely going to remember you.'
Standing ovation: Chloe was a hit with the judges as well as the live audience
