Amanda Holden channeled 60s chic in a stunning outfit when she rocked up in the capital.
The mum-of-two, 51, was papped leaving the Heart FM Breakfast studio in London sporting a cream polo neck, platform boots, checked skirt and rose-tinted glasses.
The star completed the look with a black cap as she flashed the peace sign before driving off in a bright red mini with her pals.
It's not known what prompted Amanda's fashion statement, but she certainly looked the business as she showed off her new look.
Amanda is no stranger to dressing up, having recently regaled fans with pics of her and Heart colleagues Ashley Roberts and Jamie Theakston channeling Hocus Pocus.
The trio got into costume as the iconic Sanderson sisters for Halloween after the release of the second instalment of the franchise last month.
Amanda also treated fans to another fashion moment on Instagram - although this time it was more of a wardrobe malfunction.
Fans got more than they bargained for when the Britain's Got Talent judge whipped off her dressing gown in a glamorous transformation.
Telling fans a bottle of purple shampoo was her "go to product", the star accidentally flashed her boob as she took off her white robe.
Amanda's eagle-eyed fans didn't miss a trick and were quick to comment on the mishap.
"Lovely dress but the transition needed to be more careful," one follower warned.
While another echoed: "That was a naughty tease!"
The star is currently judging BBC One's I Can See Your Voice.
However, in a preview of this weekend's show, Amanda and colleague Jimmy Carr walk off set after a cutting remark from one of the contestants.
The bonkers show, hosted by Paddy McGuinness, sees contestants try to work out which of the six mystery singers presented are good and which were rubbish – without actually hearing them sing.
The judges help members of the public eliminate the fake singers in a line-up, to scoop a cash prize.
But in a preview of Saturday's episode, Amanda and Jimmy are dismissed for being 'unhelpful'.
A player on the show called Haloo says "I love you guys but you are no help."
Following the comment, Amanda gets up from her chair and follows comedian Jimmy off set.
Host Paddy can subsequently be heard saying: "Off you go, see you later" as the duo look on - feigning frowns.
