Robert Downey Jr. Has Some Advice for Charlie Sheen (VIDEO)

Robert Downey Jr. is a former Hollywood "bad boy." The actor was known for his hard-partying ways, but now, Downey is clean and sober -- and he stays out of trouble. But there's always someone ready to fill the "bad boy" vacuum. Recently, that person seems to be Charlie Sheen. This Friday, the cops came to Sheen's hotel room, after the actor allegedly went on a drunken coke-fueled rampage. Sheen also allegedly had a naked hooker locked in his room's closet.

Will Ferrell Performs as "Celine Dion" on 'Late Show' (VIDEO)

Will Ferrell is a man of many talents. But singing is not one of those talents. Still, on the 'Late Show' (11:35PM ET on CBS), Mr. Ferrell does his best. He belts out an incredible ballad -- and he does it all for a friend. Who is Will doing his performance for? Why, singer Celine Dion, of course! As you may have heard, Celine recently gave birth to twins. Unfortunately, this meant she could no longer sing at her live Las Vegas show. Luckily, Ferrell is here to pick up the slack. Will tells David Letterman that he and Celine have been best friends for years. They met in Quebec, while sitting on a bus, while Will was in Canada during his college semester abroad. ...

Emma Stone Has Paul McCartney Design Mother-Daughter Tattoo

Easy A star Emma Stone and her mother are getting tattoos designed by Paul McCartney to celebrate her mom's breast cancer going into remission. "My mom's favorite song is 'Blackbird,' and it's my favorite song as well," Stone said on The Late Show last week. "I wrote a letter to Paul McCartney asking him if he would draw two little bird feet, because he wrote the song. And yesterday, he sent them to me." "We've never gotten tattoos before, and probably never will again," Stone added. Stone, who's hosting Saturday Night Live this week, will star in the upcoming Spider-Man reboot as Gwen Stacy, Peter Parker's first girlfriend. Source Here

Sean "Diddy" Combs Explains "Sexting" to David Letterman (VIDEO)

"Sexting" is trendy and controversial. Sending sexually explicit photos and messages over the phone has gotten some celebrities into trouble. David Letterman isn't a fan -- he doesn't understand the whole "sexting" thing. Luckily, Sean "Diddy" Combs appeared on 'Late Show' (weeknights, 11:35PM ET on CBS) and helped Dave out. Combs and Letterman discussed the recent Brett Favre scandal, in which Favre was accused of sending photos of his private parts to Jenn Sterger, a sports reporter and model. Dave was confused, so Sean smoothly explained how to go about "sexting" someone. "I'm the perfect spokesman," he said. "I'm a sex-texter myself." To Read More Click Here .

Hilary Swank Tries to Name That Tune on 'Late Show' (VIDEO)

"I like 'oldies,'" says Hilary Swank. "'60s, '70s ... I like that era." But how deep is her love for classic songs? We'll find out on the new 'Late Show' (11:35PM ET on CBS). Host David Letterman boasts of Swank's musical knowledge, and Swank confirms her encyclopedic memory for the hits of the past.

Julie Chen Brings Homework for 'The Talk' to 'Late Show' Visit (VIDEO)

Julie Chen strolled onto the 'Late Show' (weeknights, 11:35PM ET on CBS) stage with a video camera, and filmed herself hugging host David Letterman. She explained that for the new mom's roundtable show 'The Talk,' "We're given homework assignments where we have to Flip Video things that happen in our life outside of the studio." He didn't seem too thrilled about being included in the requirement, but his job is in the hands of Chen's husband -- CBS President Leslie Moonves. Speaking of, Moonves' birthday was that very day. When Letterman asked Chen how old he was, she smirked: "You and I both want to keep our jobs. You know better, Dave." He said, "But let's just say when you bring out the cake with the candles, is the fire department standing by?" Source & Preview

Bruce Willis Shows Off His Lady Gaga-Inspired "Meat Hairpiece" (VIDEO)

Actor Bruce Willis is a bald, bald man. He's been bald for so long (or had his head shaved to hide it), that we can barely remember the days when he had a full head of hair. So on the new 'Late Show' (11:35PM ET on CBS), Bruce decided to fix this problem once and for all. He showed up wearing a "meat hairpiece": a tribute to Lady Gaga's "meat dress" at this year's VMAs.

Bill Clinton on Losing Weight, Becoming a "Medical Experiment" -- Plus, a Dancing Dog! (VIDEO)

On 'Late Show' (weeknights, 11:35PM ET on CBS), former President Bill Clinton showed up to discuss his recent weight loss, and he also compared heart surgery war stories with host David Letterman. Several years ago, Bill had a quadruple heart bypass, but Dave has done him one better with his own quintuple bypass surgery. Since this operation in 2004, Clinton has become much healthier, and has tamed his love for fast food, meaning that clips like this one are no longer strictly accurate. (Although we're still big fans of the late, great Phil Hartman's Clinton impersonation.) Bill told Letterman that he now weighs the same amount that he did in high school. "You look fantastic," Dave said. To Read More Click here .

'Jersey Shore's' Snooki and David Letterman -- Together at Last! (VIDEO)

Although we think of David Letterman as being fairly "young at heart," we must admit that he's something of an elder statesman -- at least where talk show stars are concerned. Dave began his late night hosting career in 1982 -- long before the advent of, say, "Twitter," or even "The Internet." And so it seems somewhat unfair that he has to grapple with the very recent concept of "Snooki," and then figure out what the phrase "GTL" means. But that's what happens on the new 'Late Show' (11:35PM ET on CBS). To Read More Click Here .

Did David Letterman Know Joaquin Phoenix Was Faking?

Casey Affleck has admitted that Joaquin Phoenix's performance in the mockumentary I'm Still Here - including Phoenix's squirm-inducing appearance on The Late Show with David Letterman - was fake. But was Letterman in on the joke? "Dave knew about it and Dave loved it because he could play along," Bill Scheft, one of Letterman's writers, said in an interview with Nuvo magazine last year. "I've told people that [everyone was in on the joke], and not only don't people believe me, they tell me that I'm wrong and that [Phoenix] is a schizophrenic and he needs help and he's going to end up like his brother [River]. I said no. I saw the segment notes. It's an act. I saw Ben Affleck's brother taping the whole thing from offstage." To Read More Click Here .
