Walliams joins sailormen on stage

The judge, who his famous for his camp humour, teamed up with the five-piece Show Bears for their own unique take on The Weather Girls' It's Raining Men.

He told Simon Cowell the middle-aged group, dressed up in sequin-studded sailor suits and hats, could be "the new One Direction".

"I just want to join and sing that song with you; will you get me an outfit?" He joked.

Before joining them, he warned: "I may be too camp, I may send it over the edge" but joined in anyway, telling the audience: "I was in heaven."

"I just want to join you permanently and have fun with you sailor boys."

Fellow judge Samantha Holden also appreciated with the routine, telling the Show Bears: "I have just died and gone to heaven."

"I think the country is going to fall in love with you; you're so entertaining."

And Simon, who had previously pushed his buzzer, said: "Everything was rubbish but it was sort of good."

The auditions also included performances from Faceteam, a basketball stunt group from Hungary, 16-year-old singer Hope Murphy and 14-year-old singer Paige Turley.

Also making an impression were Strictly Wheels - a duo from Manchester made up of Paula Moulton and Gary Lyness - whose act sees able-bodied Gary dance with Paula who has been in a wheelchair for eight years.

They impressed the judges, with Alesha Dixon telling them they were "beautiful to watch, inspiring, refreshing, unique".
