Cheryl's daring new hair doesn't distract from her tiny figure at a L'Oreal Paris event

Cheryl Fernandez-Versini has sparked concern amongst her fans after she stepped out looking VERY slim at an event on Monday.

The 31-year-old singer was all smiles as she attended The Brush Contest held by L’Oreal Paris, a make-up competition for which she acted as one of the judges, but her already slender frame appeared TINY in a fitted Issa mini dress.

Chezza showcased her incredibly small waist when she posed for photos with winner Emma Farrell, sparking several comments from worried Twitter users.

‘Love Cheryl but she is so thin, not healthy for a woman her age to have a figure like that,’ one wrote.

Another asked: ‘Yikes! Is Cheryl ok? She’s a beautiful girl, but she’s very thin…..’

Even Cheryl‘s most loving admirers couldn’t help but mention how delicate she looked in an Instagram snap of her taking a selfie on her phone whilst having her hair done.

‘Your phone is the size of your face 😂😂,’ one noticed, whilst another added: ‘Look at your little hands😏’

Cheryl – who married French businessman Jean-Bernard Fernandez-Versini last July following a whirlwind romance – received a particularly heartfelt message of concern from one fan.

‘@cherylofficial I hope you’re ok cheryl. I wont lie, I am worried for you,’ they wrote.

‘You dont seem the same and JB’s posts are embarrassing. I miss the old cheryl. I really do. All the love xx’

Despite the worried comments from some fans, Cheryl seemed to be in good spirits at the London event and posted cute messages when she took over L’Oreal‘s Instagram page for the day.

‘Excited to meet our contestants!’ she captioned a smiley selfie.

It’s not the first time the X Factor judge has received comments about her thin frame. Last summer her husband Jean-Bernard leapt to her defence after some social media users criticised her for being too skinny.

‘She is the most beautiful woman on the planet and she wants to share it. #sharingiscaring No seriously she is,’ JB wrote.

‘And I can tell you something else she really care about her fans and touched by all your support. Now for the hater please continue talking #wasteofenergy.
