Piers Morgan is leaving NBC's America's Got Talent after six seasons, he announced Wednesday night, saying his schedule had become too hectic since he began hosting a nightly talk show, Piers Morgan Tonight, on CNN this past January.
"Turned out that juggling's harder than it looks, so I'm going to focus on CNN," he wrote on Twitter.
The British TV personality, 46, thanked NBC, production company FremantleMedia, "and of course, my friend Simon Cowell, for giving me such a great opportunity. It's been a blast."
He added: "And congrats to @MrsSOsbourne @howiemmandel & @NickCannon – you don't have to put up with me any more!"
Morgan was also one of the original judges on Britain's Got Talent, but quit that show in 2010 after four seasons to take on the CNN gig.
