David Walliams took a swipe at his fellow Britain's Got Talent judges after rumours the comedian had "argued" with his co-stars.

The 49-year-old ITV star reportedly clashed with singer Alesha Dixon over his controversial series Little Britain, according to Mail Online.

During the last semi-final on Saturday (October 3), David made a dig at his fellow judges while they talked to hosts Ant McPartlin and Dec Donnelly.

Ant asked David: "You four judges have been distanced all the way through the semi-finals, that must make it really hard to gossip about acts in between the acts."

David joked: "I've enjoyed it actually, a bit of separation."

Alesha chipped in while laughing: "You miss it really!"

"I do miss it... well yeah, we can still talk to each other, we can still hear each other", David said while chuckling.

He added: "We just can't hug and that sort of thing."

Ant and Dec spoke to Amanda about her performing a song later in the show.

David joked: "Can I read my books on the show if she's doing her song?"

The judges chuckled after David's remark

Alesha laughed: "Ashley can do a dance while you're reading a book."

Ant and Dec added jokingly: "And we can do whatever it is we do..."

David and Alesha reportedly clashed over his controversial comedy series Little Britain.

A source told Mail Online: "When the artist who Alesha had backed got through she basically turned to David and said, 'Well that's payback for all your inappropriate Little Britain antics.'

"It was quite catty, although Alesha later insisted she was only joking. But David was stunned.

"Obviously he is not racist or homophobic, or anything-phobic in the slightest — he was upset."

The insider added: "Words were exchanged, and the rest of filming was pretty awkward."

Daily Star Online has contacted representatives of Alesha and David for comment.

Britain's Got Talent airs Saturdays at 8pm on ITV.
