ALL the celebrities came to Jimmy Fallon's show last night

American TV personality Jimmy Fallon took over the Tonight Show last night. It's probably the biggest gig in American television, having run since 1954 - like their Late Late Show, basically.

So he wanted to make a good impression by asking some of his mates around. Including all of the most famous celebrities in his country.

Seriously. He starts the bit by saying the people who thought he'd never make it owe him $100 - and then they arrive one by one, in a long train of fame.

So just in case you missed any of the celebrity parade, that's:

Robert de Niro - Taxi Driver, Goodfellas etc

Tina Fey - 30 Rock, Mean Girls

Joe Namath - Former American football quarterback

Rudy Giuliani - Former Mayor of New York City

Mariah Carey - Singer, Mariah Carey

Tracy Morgan - 30 Rock, Cop Out

Joan Rivers - It's Joan Rivers

Kim Kardashian - Keeping up With the Kardashians

Seth Rogen - Comedian

Lindsay Lohan - The Canyons, Mean Girls

Sarah Jessica Parker - Sex and the City

Mike Tyson - Former World Heavyweight Champion

Lady Gaga - Singer

Stephen Colbert - Colbert Report

That must have been the very best backroom drinks ever.

And what's up with the Stephen Colbert pile of coins? They both work the same time slot as direct competitors.

As if that wasn't enough to show off his celebrity friends, not all those people were guests. And Fallon then got Will Smith to dance with him for The Evolution of Hip Hop Dancing before he took to the couch for a chat.

Then, because he hadn't already proved he knows everyone, he got U2 on the roof of the iconic Rockefeller centre to play.

Show-off.
