The longest serving judge on America's Got Talent has announced he's off via Twitter.

Piers Morgan has been on the panel since the first season way back in 2005. But he told his 1.4m Twitter followers last night that he wants to concentrate on his other job, his talkshow Piers Morgan Tonight.

"I'm leaving AGT after six wonderful years", he tweeted. "Turned out that juggling's harder than it looks, so I'm going to focus on CNN."

He also thanked "his good friend Simon Cowell" and said his time on the show had been "a blast".

Only yesterday did we report the groundbreaking news that Su-Bo ain't judging no talent show bruv. That's what she would say if she were street. And fifteen.
