Amanda Holden caught the eyes of Britain's Got Talent viewers during the show's first semi-final of the series on Monday as she wore a revealing claret red dress.
The radio host, 53, joined her fellow judges - Alesha Dixon, Bruno Tonioli and Simon Cowell - but stood out as she chatted to hosts Ant McPartlin and Declan Donnelly during the opening minutes of the live episode.
Actress Amanda looked glamorous in her one-shoulder gown which featured sleeves with attached gloves.
The garment's material gathered to the front but it was for another reason that fans of the show focussed their attention on the dress - many took to social media to note that they could see her nipples through the material.
They joked it must have been cold in London's Hammersmith Apollo where the semi-final was taking place.

The winner will get a life-changing £250,000 cash prize and a spot on the bill of the Royal Variety Performance.
The eight acts who performed on Monday night were Sven Smith, The Trickstars, Trey Braine, Sslaubi Performance Troupe, Taryn Charles, Bikoon, Stardust and Innocent Massuki.
Also performing on Monday night’s show was the West End cast of Disney’s award-winning musical The Lion King.
It comes after Simon and Amanda's children pushed the golden buzzer on Britain's Got Talent as the auditions for the series came to an end on Sunday.
During the episode, Japanese skipping dancers Haribow, who somersaulted across the stage doing various tricks, left the judges almost speechless.
They received a standing ovation from the audience and numerous pleas for a golden buzzer, which would put them straight through to the semi-finals and are generally used only by the judges and hosts, from the BGT fans.
Alesha said she had 'none left' regarding the buzzers along with Bruno, while Simo said that he 'did not know what to say'.
'My son is literally going crazy right now,' Simon added.
