Amanda, aged 51, flaunted her age-defying physique as she posed in a figure-hugging white mini dress on Sunday night.

Radiating glamour, the TV star looked resplendent in the form-fitting attire, accentuating her waistline and featuring a plunging neckline that highlighted her alluring cleavage.

To complement her ensemble, the mother-of-two adorned herself with matching white gloves and a pair of elegant white Louboutin heels.

Her luscious blonde locks cascaded straight down, perfectly complementing her glamorous makeup, which showcased false lashes and a nude lip.

Amanda enthusiastically posed for a variety of shots while filming a new episode of Britain’s Got Talent at the iconic Palladium theater in London.

Captivating the camera, she first perched herself on the theater’s marble staircase, exuding an air of grace and sophistication. In a subsequent shot, she confidently walked away, showcasing her tanned and toned legs, which drew attention to her peachy posterior.

A third photograph captured a close-up, as Amanda struck a playful pout, exuding confidence and charisma.

This latest display of Amanda’s enviable pins follows her recent public appearance in a navy blazer dress, where she stunned onlookers by showcasing her tanned legs and wearing high heels while being chauffeured to film the new ITV talent series.

In a candid snapshot taken inside the car, Amanda effortlessly propped her legs up on the passenger seat, appearing engrossed in a phone conversation.

Later, she was spotted alongside her fellow BGT co-star Alesha Dixon, once again putting her leggy allure on full display as they left the filming location.

Despite rumors of a pay dispute regarding new judge Bruno Tonioli, Amanda and Alesha presented a united front as they posed on the red carpet.

Alesha captivated onlookers with her striking leather dress, while Amanda’s radiant presence added to the star-studded affair.

With Bruno joining the judging panel, the former Strictly star will replace former judge David Walliams, who departed from the show last year.
