Amanda Holden debuts sleek bob as she stuns in a red mini dress for Britain’s Got Talent’s live semi-final

Amanda Holden debuted a stylish bob in a gorgeous look at Saturday’s live semi-final of Britain’s Got Talent.

The 55-year-old TV star looked sensational as she embraced her striking new look after chopping off her long wavy tresses.

Amanda put on a very leggy display in her tight red mini dress alongside judge Simon Cowell, 66, Alesha Dixon, 47, and KSI, 32.

The dress featured a boldly plunging neckline and was cinched at the waist with a striking gold belt, which was reflected in her statement earrings.

Ahead of the show, Amanda took to Instagram with a fun clip of herself imitating Miranda Priestly (Meryl Streep) in The Devil Wears Prada, where she was the assistant to music mogul Simon, played by Anne Hathaway in the film.

Looking nothing short of incredible in the back of her car, he looked with disgust at her trademark black outfit as he re-created the iconic scene and said: ‘Emily, that’s it.’

Amanda arrives after sizzling in a daring backless dress while drinking champagne on a boozy night out with Alan Carr at the BAFTA TV party in London on Wednesday.

While striking stormy poses, she attracted attention with her dramatic, transparent black evening dress with a hot, high-fashion line.

The front of the dress featured a halter neckline with a deep V-neck and black lace details under the bodice of the dress.
