The 46-year-old Britain’s Got Talent bombshell opted for a chic navy jumpsuit for the occasion as she hit the town with several girlfriends to celebrate former Coronation Street star Angela Griffin’s 41st birthday.
Dressed to the nines in the stylish backless number, Amanda Holden shared a cheeky clip with her 563,000 Instagram followers, wiggling her behind for the camera to show the outfit off to outs full effect.
She wore her platinum locks in a tousled, bedhead style and paired the ensemble with towering stiletto heels.
Later in the night, the party headed to the central London hotspot to enjoy a bit of singing and dancing, with Amanda joining Angela and another friend on stage to belt out Madonna’s Like A Virgin.
The group seemed to be having a great time as they giggled and wiggled, putting on a good show for onlookers.
Amanda flashed plenty of sideboob in her racy jumpsuit, opting to go braless under the revealing garment.
Earlier this month, the ITV favourite came under fire for her “frozen” appearance during her guest presenting appearance on This Morning.
Standing in for Ruth Langsford, 47, and Eamonn Holmes, 47, Amanda took her place on the sofa alongside Ben Shepherd, 42, to host the show, but viewers were left more than a little distracted by her appearance.
“Frozen faced #AmandaHolden sitting there like she’s on a photo shoot,” one fan tweeted, while another slammed her presenting skills, saying: “Get Amanda Holden off #ThisMorning she is the worst presenter.”
