The Jonas Brothers have a hippopotamus named after them thanks to an animal-loving fan who adopted the mammal in their honour.
The Lovebug hitmakers admit they have had some weird and wonderful gifts from their adoring fans in the past, but the big animal tops the list.
Joe Jonas says, "A hippo was one of our gifts once. Somebody adopted a hippo in our name, so that was pretty amazing."
But they have no idea where in the world the Jonas Brothers hippo lives.
Joe adds, "I'd love to visit one day."
