Those who missed Sharon Osbourne's risque antics while 'The Talk' (weekdays, syndicated on CBS), was on hiatus were treated to quite the return when Nick Cannon stopped by the show Wednesday. Cannon and Osbourne are host and judge, respectively, on 'America's Got Talent,' and Cannon reported that Osbourne is just as wild behind-the-scenes of that show as she is on 'The Talk.'

Cannon recalled Osbourne's trademark excited voice and her propensity for practical jokes. "She is hilarious," he said. "I love when she just blurts out stuff with that high-pitched register. That's amazing. But, when we're just hanging out, like when we're traveling and stuff together, she is the jokester."

One specific prank happened on an airplane when most of the cast was asleep. Osbourne told Cannon to have his camera ready. "She literally goes up to Piers Morgan, who's like, asleep, drool hanging out of his mouth," said Cannon, "and, can I say, she pulls out her breast and puts it right on Piers Morgan's face." Cannon said it was the funniest thing he'd seen in a decade. We wonder how Piers felt about it.
