Leave it to Jimmy Kimmel to pack all of his celebrity friends into one epic movie trailer!

During the late night host's post-Oscars show, Kimmel debuted the hilarious trailer for Movie: The Movie.

Anybody who's anybody is in there ... including Tom Hanks, George Clooney, Cameron Diaz, Jessica Alba and Matt Damon. Loves it!

Let's hope Jessica Alba's hubby Cash Warren is cool with this! We have feeling he knows that if Jimmy Kimmel is involved, it's all in the name of comedy.

During a skit on Jimmy Kimmel Live, the pregnant starlet attends a birthing class with the late night host and discusses everything from opening up your vagina during the birthing exercises ... to perineal massage.

With Jimmy and Jessica, nothing is off limits!

Men everywhere have dreamed of this moment -- getting a big, wet kiss from Charlie Sheen ... NOT!

Unfortunately for late show host Jimmy Kimmel, he got just that last night when Charlie made a "surprise" appearance on the show during an interview with HDNet owner Mark Cuban.

Sheen is reported to be in talks for his own show on the network (one of the three networks reportedly chatting with the fallen actor for his own talk show).

Sheen took the opportunity to promote his new t-shirts with his famous slogans about tiger's blood and "winning." He then told the audience he had to leave to write his show, referring to his upcoming stage tour which will see him on an empty stage with nothing but a stool, a microphone and a bottle of water, according to reports.

Check out Charlie's tornado-like appearance ...

Jimmy Kimmel let it rip last night on The Jay Leno show, showing Leno no mercy.

Jimmy had previously hosted his own late night show on ABC in character as Jay Leno. Leno returned the favor by inviting Jimmy on The Jay Leno Show last night as part of his "10 @ 10" segment in which Leno asks 10 questions of his choosing. Big mistake.

When Leno asked Kimmel what his favorite prank was, Kimmel responded, "I told a guy that five years from now, I'm going to give you my show, and then I gave it to him and took it back almost instantly." Kimmel continued, "I think he works at Fox or something now."

Then Jay asked, "Ever order anything off the TV?" Kimmel responded, "You mean the way NBC ordered your show off the TV?"

But it didn't stop there. When asked about strippers, Kimmel said, "I don't like strippers because you have a phony relationship with them for money. Sort of like the way you and Conan were on The Tonight Show together passing the torch? You know what I'm saying."

And in a final plea for Conan's job back, Jimmy said, "Listen, Jay, Conan and I have children. All you have to take care of is cars. We have lives to lead here. You have $800 million. For God's sake, leave our shows alone!"

We caught Sarah and Jimmy, both with fast food in hand, last night after the GQ party -- doing their best NOT to be photographed together (we DO have Photoshop you sneaky comedians!). But is this couple really a couple?

See what Sarah had to say about it yesterday before the party. This is why she makes the big bucks, y'all! Listen to this -- THIS is comedy, people!

Spotted: Sarah Silverman and Jimmy Kimmel out in Malibu, looking happy as can be.

Maybe they never broke up in the first place? Who knows with comics!

And from that enormous smile on Sarah Silverman's face, I'd say she's pretty darn happy about it!
