Prime Minister Gordon Brown has appeared on America's version of Pop Idol - but don't worry, he wasn't singing!
In a video, which was filmed for a special charity version of the talent show, Mr Brown promised cash to help fight malaria in Africa.
He promised 20 million mosquito nets to help protect people from the disease, which is carried by the insects.
Mr Brown said there was "nothing more amazing than saving a life".
It's thought around 3,000 children die each day from malaria, most of them in Africa.
Mr Brown, who is a fan of talent shows, told TV viewers: "All year on Idol, it's the talent of the American people we admire. But tonight, it's your generosity."
