Simon Cowell has suggested that he may shake-up the judging panel on next year's Britain's Got Talent.

Up until now, the panel has consisted of Cowell, Alesha Dixon, Amanda Holden and David Walliams since 2012. Previous judges include Michael McIntyre, David Hasselhoff and Piers Morgan.

But speaking to Bang Showbiz, Cowell explained: "I'm possibly looking at a shake-up for next year. It's about having a conversation to see how much they want to be on the show."

"Are they still into the idea of finding a star? I never want a judge for hire. I want someone committed."

Speaking about his relationship with David Walliams, Cowell said that the comedy actor had overstepped the mark on a few occasions with some of his comments. 

"He gets really over-excited on the live shows and says and does things he wasn't planning, then sometimes regrets it," Cowell remarked.

"But he kind of makes it interesting.I knew what I was getting when I hired him."

This year's Britain's Got Talent 2014 final saw the five-piece act Collbaro win. The operatic boy band took home £250,000.
