Simon Cowell and David Walliams bicker over helicopters and kids' names on Britain's Got Talent

Simon Cowell and David Walliams bicker over helicopters and private jets during \'Britain\'s Got Talent\' auditions.

The two judges clashed on the panel in a playful row during audiences over the weekend, with the media mogul taking a dig at his co-star after an ego-friendly children\'s choir sang about global warming and single-use plastic.

As reported by The Sun newspaper\'s Bizarre column: "I hope, off the back of this David, that you don\'t use your helicopter any more to come to work.

"Take a little sign from these kids and think, you know what, cycle."

However, David quickly fired back: "I have seen a picture of you on a jet ski. You flew here today by private jet and you are 10 minutes away by car."

The tongue-in-cheek argument continued, with Simon joking he was taking the comedian\'s copter away.

He teased: "I know it is in your contract. We are now taking it out, you are not coming by helicopter any more."

The pair also clashed after Simon accidentally called David\'s son Alfred by his dog\'s name.

After a kid\'s entertainer took to the stage, the boss quipped: "Why don\'t you book her for your son Bertie\'s next birthday?"

Pointing out the error, David joked: "Bertie is my dog. I would expect you to know the name of my son. If you bothered to send a card or a present..."

However, Simon didn\'t waste any time pointing out that his fellow judge has made a similar mistake in the past.

He said: "You called Eric Squiddly once, if you remember."
