Britain’s Got Talent judge Amanda Holden absolutely slayed in a purple thigh-split dress during last night’s live semi-finals.

The 51-year-old panellist, who was recently praised by Kirstie Allsopp for defending her on the ITV series, set pulses racing in the leggy number as she returned to the Hammersmith Apollo.

The straps and bust area of Amanda’s head-turning gown boasted of silver embellishments, with the detailing also visible around the thigh.

She paired the number with nude heels, adding inches to her petite frame.

Amanda posed for a series of snaps ahead of the show airing with her hand placed on her hip, and it’s fair to say she looked fierce as hell.

Celebrities were in awe of the personality’s look at rushed to shower her in compliments.

Good Morning Britain’s Susanna Reid and Louise Redknapp also sent compliments in the form of fire and love heart emojis.

Last night’s episode of Britain’s Got Talent saw impressionist Ben Nickless and musical duo Flintz and Taylor sail through to the final on Sunday after the second live semi-final show.

Ben was put straight through after receiving the most audience votes, while Flintz and Taylor went head-to-head with Amber and her dancing pets act, but Amanda’s co-stars David Walliams, Alesha Dixon, and Simon Cowell all voted to put them through.
