Late Show with David Letterman

We always expect a laugh when Amy Poehler appears on a late-night talk show, but last night she was exceptionally funny. While appearing on the Late Show with David Letterman to promote the season premiere of Parks and Recreation, the working mama discussed life with her two boys — Archie, 3, and Abel, 1 — who she says are both rather large for their ages. She went on to describe her desire to carry them in a baby carrier when they were smaller, but explained that the process simply didn't work for her. Watch the clip and tell us — did you have trouble using one of the devices?

Tom Cruise swung by the Late Show in NYC yesterday to chat with David Letterman about Mission: Impossible — Ghost Protocol. The guys spoke about Tom's Interview With the Vampire costar Brad Pitt, then moved on to chatting about how Tom manages to relax between moviemaking, promoting, and traveling. He said, "Well. . . we have weekends!" Find out how Tom, Katie Holmes, and Suri unwind on Saturdays and Sundays.

Matt Damon has been sporting a shaved head for his role in Elysium lately and he took the look on the Late Show With David Letterman last night. Matt talked about how his baby daughter, Stella, reacted to his head by treating it like a drum. Hear the funny story when you watch now!

Emma Watson addressed the partying habits of her Harry Potter pals yesterday while on The Late Show with David Letterman. When asked about her own drinking routines, the proper English actress adorably dodged the question for a while until finally admitting to having gotten drunk on one occasion.  The actress first assured everyone that she was of legal age and then proudly stood up and took a bow — check it out below!

While Patrick Dempsey was busy promoting Transformers 3 on The Late Show With David Letterman last night, Letterman couldn't resist changing the subject to Grey's Anatomy. He asked Dempsey to address the rumors that he's done with the show, to which Dempsey reiterated that his contract is simply up after next season and could definitely be renewed. He also tells Letterman that he shouldn't be that worried about a Seattle Grace without McDreamy, but I think we'd all feel a lot better if ABC made it official. Watch!

Shia LaBeouf stopped by The Late Show With David Letterman last night as his promotional tour for Transformers: Dark of the Moon kicks into high gear. After a quick update about how he's doing with that injured hand of his, Letterman moved the conversation right along to the important issues: LaBeouf's female costars. When asked how Megan Fox came to be replaced by Rosie Huntington-Whiteley, LaBeouf reveals how they wrote Fox's character out of the movie (and no, Michael Bay didn't kill her off). Check it out.

One of the hottest exercise trends (literally) is Bikram Yoga. On The Late Show with David Letterman, Jason Bateman tells the story of actually working with Bikram himself when he was a kid growing up in Los Angeles. The memory isn't exactly a happy one for Jason, but in classic Jason Bateman fashion he retells the story of being in Bikram's class, and he brings along a picture of him with Bikram to prove that he was there.

Cameron Diaz finally spilled the details about that infamous photo of the actress feeding boyfriend Alex Rodriguez popcorn at last year's Super Bowl. She told David Letterman last night that she doesn't like people putting their hand in her food. Maybe she just doesn't like sharing her food, but I think it sounds more like she has some germaphobe tendencies. I wouldn't have an issue with sharing eats with my significant other, but when it comes to hygiene rules in relationships people seem to fall somewhere on a scale: on one end you have sharing a toothbrush, and on the other end you're using separate straws. I'm somewhere in between; where are you?

Watch Cameron tell the whole story now!
