More than 100 of the world's biggest stars took part in a charity event to raise money for the millions of people affected by the Haiti earthquake.
Fantastic Mr Fox star George Clooney hosted the Hope For Haiti Now telethon, which was broadcast all over the world.
Taylor Swift, Rihanna and Madonna all performed on the night, while the Jonas Brothers were among the stars answering phones to take people's donations.
All the money raised will go to relief organisations, like the Red Cross.

It's thought three million people have been affected by the earthquake, including 1.5 million who are now homeless.
The official death toll has also risen, to 110,000 people.
George Clooney was one of the organisers of the two-hour Hope For Haiti Now event and said everyone needed to do what they could to help.
"It's a big world out there, and we all have a lot of responsibility to look out for people who can't look out for themselves," he said.
Donations from some of the stars taking part already add up to millions of pounds for the relief effort, but it's not yet known how much was raised in total on the night.
