Piers Morgan quits "America's Got Talent"

(CBS) Talk show host Piers Morgan is quitting the judge's panel on "America's Got Talent."

The 46-year-old British journalist and TV presenter made the announcement Wednesday night on his CNN talk show, "Piers Morgan Tonight."

Saying he couldn't juggle his busy schedule any longer, Morgan thanked his friend Simon Cowell, the show's creator, and congratulated his "Talent" co-hosts Sharon Osbourne and Howie Mandel. He also mentioned show host Nick Cannon.

Morgan has been judging the NBC summer-season talent show since 2006. He also was a judge on the British version of the show with Amanda Holden and Simon Cowell. The U.S. show is based on the U.K. version.

CNN tapped Morgan in January to host a show that would replace "Larry King Live," a staple of its weekday primetime lineup.

Morgan told viewers his lighter schedule could make him available to host the 2012 Oscars ceremony in February, now that Eddie Murphy is out.
