"What a night it was!" she exclaimed on Instagram.
The One Show host Alex Jones has been busy being a mum to two little ones since giving birth to baby Kit earlier this year.
But we imagine she relished the opportunity to have a night out on the town this week, donning a super glam floor-length dress for the John Paul Gaultier Freak Show play, where she rubbed shoulders with the A-list and even stopped for a chinwag with the man himself.
And while Alex's stunning gown may have looked as high fashion as her surroundings, her dress was actually a bargain high street buy from Zara.

Alex couldn't resist a cheeky Insta post during the big night, and was pictured posing for a selfie, beaming next to a friend.
She captioned the post: 'First night out since having Kit last night and what a night it was! Thank you to the cast of @jpgfashionfreakshow for putting on such an incredible show and of course to the man who loves a stripe nearly as much as I do #jeanpaulgaultier.
'He was really down to earth and chatted for ages about how he originally designed his trade mark cone corset for his teddy bear when he was just 9 years old!'
Despite having a brilliant night out on the tiles, it's clear that Alex couldn't wait to get back home to her family.
She finished the post by writing: 'Back home by 10.30 due to impending exploding boobs and desperate for a cuddle but nice to have a few hours of glamour! #fashionfreakshow'.
