"How Do You Know" stars Paul Rudd, 41, and Owen Wilson, 42, both laughed it up at the film's L.A. premiere this week.


Question is ...

"Dinner For Schmucks" stars Paul Rudd, 41, and Steve Carell, 47, both showed up to the film's premiere in NYC on Monday.

...the mere suggestion that Paul Rudd should jump off the movie star gravy train he's riding to pick up a gig on a reality show!!!!!!

Apparently our photog hasn't seen Paul's IMDB lately -- dude ain't struggling to pay the bills.

Paul Rudd and RuPaul are similar only in name -- and yet our photog asked if the two were ever mistaken for one another.

So you've got Seth Rogen, Jonah Hill and Paul Rudd -- three of the, arguably, funniest guys out there right now -- why the hell ask them about Ashlee Simpson & Pete Wentz's engagement?!

Also in L.A.: Mila Kunis, Kristen Bell and McLovin' all blew off fans outside the Kodak Theater, Rumer Willis had her very own pap crush, Kevin Richardson was mistaken for another Backstreet Boy and Kim Kardashian got a public berating by her own sister.

In NY: Michelle Trachtenberg dodged questions about rumored BF Chace Crawford, Kiefer Sutherland went out with his new chick, and Ben Stiller struggled to remember the name of Derek Zoolander's infamous pose.

Oprah Winfrey, James Gandolfini, Susan Sarandon and Tim Robbins all turned out for the much-hyped premiere of 'Three Days of Rain' -- Julia Roberts' Broadway debut.

"It was just a great opportunity and I was up for the challenge," Roberts said.
