JAY MOHR'S JUNIOR PARTY PLANNER

Now that comedian Jay Mohr has popped the question to Las Vegas's Nikki Cox, his best man—3-year-old son Jackson (mom is actress Nicole Chamberlain)—knows how to celebrate. "His bachelor party would be Big Wheels, a little Thomas the Tank Engine and then jumping off the furniture yelling, 'Infinity and beyond!'" says Mohr, whose comedy series Action is now on DVD. "Once in a while he'll mix it up and yell, 'Guacamole and cheese!' I have no idea [why], but it has the same result: a cannonball into my solar plexus followed by insane laughing."

NICK CANNON: UNPUNKABLE

Punk'd creator Ashton Kutcher may have met his match in pal Nick Cannon. "They've already tried to punk me four or five times," says Cannon, 25, whose MTV comedy show Wild 'N Out just began its second season. "Ashton's mad," he says. "They need to just give up; I know it's getting expensive." The most recent thwarted attempt came just a few weeks ago: "They put somebody up to act like they were trapped in this gas station bathroom, but I found all the cameras, the lighting, the grip wires and the bad actors. I was like, 'Come on, man, I'm a TV producer. I know what a lipstick camera looks like!'"

MOORE: GO, BO!

While Julianne Moore was filming Freedomland —about a woman whose young son is missing—costar Samuel L. Jackson says she was often preoccupied, but not by the horrifying thought of losing a child. "Julianne was caught up in American Idol at the time," says Jackson, 57. "We'd be standing there ready to shoot, and she'd be like, 'Bo was singing so good last night!' Then [director] Joe [Roth] would say 'Action!' and she would start crying. As soon as he'd say, 'Cut!' she would go, 'I really hope he wins!'"

THREE QUESTIONS FOR ...
SARAH JESSICA PARKER

She's starring in Failure to Launch.

It involved two weddings. Two weddings and no funerals.

3 DID YOU DRIVE YOUR SATC COSTAR JOHN CORBETT INTO A SINGING CAREER?
Is he not acting? What's happening with that album? Is it happening?

YES. IT'LL BE OUT APRIL 4.
