The Geordie Shore star turned heads at the central London studio on Sunday evening (10 November) wearing the flirty Alice frock by Lola Loves, £210.
We love this look!
Charlotte's been all over our style radar in recent weeks, rocking everything from chic white to oversized checks to elegant leggings and wraparound shirts.
We can't wait to see what she wears next!
The bubbly brunette was on Xtra Factor as one of the celebrity panelists discussing the latest result, which saw Abi Alton eliminated over Hannah Barrett. Surprisingly, she told Caroline Flack and Matt Richardson she'd have sent home Nicholas McDonald out of all the contestants.
"I do think he's an amazing singer. I just feel he has too much of a baby face. I just feel like he hasn't got the X Factor," she explained. "It's not an 'ahhh' factor. It's an X!"
Charlotte also shared her thoughts on one of the most talked-about contestants of the series, Sam Callahan, who is still very much in the running despite critique from the judges and some viewers that he isn't the best singer.
"I don't think Sam will ever go," said Charlotte. "You'll never get rid of him. He has such a big fan base. He's a good looking lad. You know what crazy young girls are like. Stalkers! He's not going anywhere!"
Charlotte later cosied up with X Factor contestant Sam Bailey, the only remaining member of the Over 25s category.
X Factor continues Saturday on ITV.
