Myleene Klass rocks colourful '80s make-up and a throwback perm for Keith Lemon's star-studded fancy dress birthday bash

She's known for her elegant style and bronzed look.  

But Myleene Klass made a bolder statement when she posted an Instagram picture of herself in pink and yellow '80s-style make-up, before appearing on ITV's Keith Lemon's Celebrity Juice birthday special on Thursday night.

The 38-year-old teamed striped eye-shadow with a frosted pink lip, captioning the much-liked post 'Asked @karindarnell for full on, 80's make up......#result #celebjuice', before filming the episode.

Throwback: Myleene Klass sported full '80s-inspired make-up for Keith Lemon's fancy dress birthday bash - sharing the hilarious snap on Instagram on Thursday evening

The classical musician teamed her striking make-up with pink heart-shaped pendant earrings - but kept her trademark Leenie necklace for the event. 

She wore her normally wavy hair in tighter curls, inspired by the era's trend for perms.   

She rounded the look off with a purple, green and pink ruffled bandeau dress, which allowed her enough movement to play the piano with her arms behind her back.  

Myleene, who has appeared on the cheeky game show a number of times, appeared alongside other guests Billy Ocean and the star of '80s cult classic Gremlin,  Zach Galligan.

Myleene, 38, joined the show's team captains along with Billy Ocean (centre) and Gremlin's actor Zach Galligan (third from right) 

And while Myleene sat having her make-up done, long-time team captain Fearne Cotton also shared her preparations for the big day. 

The presenter, who has been on the ITV show since 2008, posted an energetic Instagram video of herself dancing in her '80s outfit. 

The 34-year-old donned her eighties best with a scrunchie and clunky gold jewellery whilst channeling the iconic material girl, Madonna in the short video clip.

Captioning the video: 'Tomorrow on celebrity juice it's Keith's birthday and we go all 80's. 

I chose @madonna from the hair scrunched decade and pulled my knee out doing this. #cantfindthestopbutton styled and filmed by @sineadmckeefry.'

Dancing along to Madonna's 1982 hit Everybody, she sashayed along in a pair of black harem pants and cropped blazer with scrunched padded shoulders.

Her tightly curled blonde tresses were scooped back with a large black hairband, reminiscent of the trendy era. 

The low neckline of her ensemble allowed her long chain necklaces to bounce upon her ample cleavage as grooved side by side.

Raising her legs in excellent sync to Madonna's original moves, her efforts were cut short- probably due to the issue with her knee, which she explained under the video.

The fun video racked up 12.4k likes with one user, @sonomaddiemooLove stating: 'Loved it! @madonna is my idol, love her. There's something about you that reminds me of Madonna anyway. You got the dance moves down!'

Another follower @icedjem6 commented: 'Yeah before I even read your post I thought 'like a virgin' you got the moves girl!'

Her eighties look can be put down to the visionary talent of stylist Sinead McKeefry who has also styled her ITV co-host Holly Willoughby. 

Regular: She's been a team captain on ITV's Celebrity Juice since 2008 alongside Holly Willoughby and host Keith Lemon 

Whilst, she has been actively preparing for Keith's birthday, the eccentric host recently lamented both Fearne and Holly for taking so much maternity leave.

Feanre, who is mother to Rex, 3, and 7 month old Honey, revealed: 'There's no more babies, we're done.'

The radio presenter has managed to snap back in to shape rather quickly, which was evident at the recent Rolling Stones exhibition launch.

Posing alongside her hubby Jesse Wood, Fearne wore a crisp white blouse which fell open to reveal her sheer black bra- almost resulting in a wardrobe malfunction.
