Amanda Holden, 47, certainly stood out as she headed to the Lowry Theatre as she went braless in the bright one-shouldered garment.
Posing on the red carpet, the star looked glowing as she displayed her gym-honed physique in the figure-hugging gown which featured a dramatic cape detail on one side.
Amanda flaunted her slender curves and showcased her toned, defined arms as she posed up a storm.
The age-defying beauty teamed the eye-catching look with a pair of white pointy heels.
Amanda left her blonde locks in tousled waves and added some more glamour with smoky eyeshadow and a nude lip.
Her co-star, Alesha Dixon, 40, was equally as striking in a monochrome jacket, which she wore with a pair of flared black trousers.
The singer went on to remove her outer layer to unveil a plunging Balmain bralet underneath.
Alesha completed her outfit with a pair of strappy back heels and showcased her sense of style by wearing just one huge earring.
The Britain’s Got Talent judge swept her locks away from her face in a half up, half down do’.
Amanda and Alesha went on to pose for photos with their fellow judges Simon Cowell and David Walliams.
Ant and Dec also joined the group and smiled away as they prepared to head into the theatre.
The Geordie duo reunited for the ITV series in January, in their first work commitment together since doing the auditions round last year.
Ant stepped out of the spotlight for a year and took time off after he was convicted of drink driving.
As they returned to work last month, the pair shared a selfie to their joint Ant and Dec Instagram account where they said the “boys are back”.
The presenters couldn’t have looked more excited to be filming for Britain’s Got Talent again as they beamed to the camera.
They captioned the snap: “#BGT 2019. Audition day 1. The boys are back in town!”
Last week, the TV favourites revealed they were filming the promo for Britain’s Got Talent.
The pair shared an image of themselves posing in extremely smart attire whilst holding a conductor’s baton.
They wrote beside the image: “Shooting the #bgt promo. All together now, a – 1,2,3,4.”
Britain’s Got Talent 2019 is expected to return to ITV this Spring.
