Conan O'Brien

It’s still the best way to see a film.

Here’s who will be vying for all of this year’s Oscars.

It's September 11, which means it has been 12 years since the 9/11 terrorist attacks, a day the citizens of the United States promised never to forget because much like the North, America remembers. Cue all the celebs of Twitter tweeting their memories and honoring those who were lost.

When Mike Tyson is having lady problems he calls his friend Justin Bieber. No, really.

Late-night host Conan O'Brien was pretty miffed about how Kate Middleton and Prince William barely showed off their as-yet unnamed baby yesterday (July 23), bemoaning the fact that they didn't do it with enough style. Which prompted him to show them how it's done.

Today (July 11) was a convenient day for the celebs to be out getting Slurpees at their favorite convenience store. Some of them were also catching up on their favorite shows, tweeting photos from the set and coming up with crazy movie remake ideas. That is when they weren’t making up salacious rumors about their own husbands (we’re looking at you, Ali Wentworth).

The Twitterverse was fairly quiet today (July 9), what with it being Tuesday and all, but that didn't mean all the celebrities kept their 140-character-or-less thoughts to themselves.

Kesha was her usual adorably wacky self on 'Conan' last night. To wit: She wore a booty short/three-piece suit with host Conan O'Brien's face all over it, and then she talked about the weirdest things possible.

Saturday night (April 27) was the annual White House Correspondents' Dinner, which hosted many important faces in the political sphere, as well as celebrities ... and the cast of 'Duck Dynasty.' (No, we're not sure how that happened either.) This year, the star-studded event was headlined by Conan O'Brien, who had the distinction of leading the event once before in 1995 for President Bill Clinton.

The iconic Willie Nelson is either well into or gearing up for his 80th birthday (some say it's today, April 29, but the state of Texas and its fancy paperwork says it's tomorrow) -- and he's recorded a special audition reel for Peter Jackson just in time for the occasion.

Russell Brand is a comedic genius, albeit one who's utterly insane. Proof? Last night, April 16, he went on 'Conan' and talked about, among other things, a foursome with the Kardashians, how he'd sleep with Jennifer Lawrence (who wouldn't?), using hypnotism to stop his sexual desires, and convincing Tom Cruise to convert him to Scientology.

Chelsea Handler, host of 'Chelsea Lately,' went on 'Conan' to talk to Conan O'Brien about their recent nude shower sketch -- which Handler credits as putting O'Brien on the sexy map -- and a run-in with Jessica Simpson's baby shower.

After Justin Bieber angered everyone (well, almost everyone) by hoping that teenage holocaust victim Anne Frank would have been a Belieber, the writing staff at 'Conan' decided to imagine what it would be like if the tween sensation wrote messages to other historical figures. Watch out, Joan of Arc, Jesus and Martin Luther King Jr. -- faux-Justin Bieber is about to be insensitive, and you're the t

Charlie Sheen made perhaps the best entrance ever onto the 'Conan' sound stage last night (April 11), climbing out of a tank with two scantily clad ladies. The reason? He hasn't been on the Warner Bros. lot since his infamous fallout with Chuck Lorre, the creator of 'Two and a Half Men,' and he wanted protection. It's as good a reason as any.

Once upon a time, comedian Adam Sandler had a dream -- a dream that he'd get to see Shaquille O'Neal's penis. Most people want to be an astronaut, but you know.

Way back when Conan O'Brien was on NBC's 'Late Night With Conan O'Brien,' there was a running gag that he was really big in Finland because of his striking resemblance to the 11th Finnish president, Tarja Halonen. Remember this? Nostalgia!

Conan O'Brien may have had a few brief moments (okay, a year) as 'Tonight Show' host before the role was taken back from him by the so-called retired Jay Leno, but that didn't stop him from being happy for fellow late-nighter Jimmy Fallon, who was announced as Leno's replacement yesterday (April 3). This of course was not the case on 'Chelsea Lately,' where he and Chelsea Handler get in a naked sh

For April Fool's Day in 2012, late-night host Conan O'Brien released a video claiming he'd purchased the tech website Mashable for a mere $3,500 (because it's terrible) and had already fired the site's CEO, Pete Cashmore.

A regular segment on 'Conan' called "If They Melded" takes a look at what would happen if two celebrities faces were mashed together (after maybe a horrible radioactive spill of some kind, we're guessing). Warning: You may not sleep tonight. Especially when you see what would happen if Anne Hathaway and Lord Voldemort joined forces in a dark alley.

In our Celebrity Tweets of the Week, Ellen goes to bed before dark, Conan O’Brien plays seismologist, John Stamos caught someone playing fast and loose with Photoshop, Diddy got nostalgic, jokes about the new Pope abounded -- and a whole lot more.
