Caroline Flack sure knows how to embarrass her pals.
The Flackster has taken to Instragram to post a TBT of her X Factor buddy Nick Grimshaw looking realllllllllllllll cool.

We're not sure exactly when the photo was taken, but judging by the fact Grimmy’s got an actual perm, we’re guessing around 1981.
Looking good, buddy…
X Factor London auditions outfits

Rochelle Humes
Mrs Humes looked amazing in her crisp white Iris + Ink playsuit teamed with leg-lengthening heels and a chic pony

Rochelle Humes
Looking like she's stepped straight out of a '90s girl band in her cool American Apparel dungarees

Cheryl Fernandez-Versini
Chezza's loving her retro '60s vibes during the auditions so far, and her cute Miu Miu shift and matching pink heels look gorge on her

Cheryl Fernandez-Versini
Cheryl's Adam Lippes tuxedo dress may cost over £1k, but that's nothing compared to a lifetime of dry cleaning bills. Just beware of Nando's, eh Chez?

Rita Ora
B*Witched would be soooo jealous of these denim co-ords. Rita continues to show off her risky fash sense on the red carpet

Rita Ora
Poor Rita must've accidentally got stuck in a door or been attacked by a pack of dogs on the way to the auditions. We can think of no other possible explanation for that missing sleeve

Caroline Flack
Working Beatnik chic in a cute striped top and leather mini

Caroline Flack
Caz doesn't half love a boyish short and shirt combo. She picked up these snakey platforms for just £52 from Toppers!
