Pop trio The Jonas Brothers gained an extra member this week - their younger sibling Frankie. The seven-year-old - known by his nickname of Bonus Jonas - joined his older brothers for an appearance on MTV's Total Request Live.

And the youngster unashamedly stole the show from his famous family, by revealing he is planning to launch his own band to rival his brothers.

And Joe Jonas is adamant that Frankie's first venture into showbusiness will have the whole family's support.

He says, "He's always telling us that his band he's making ... he's always saying, 'You guys are going to open for me.' He's a funny little guy."

And Joe adds that Frankie already has strong opinions on music - insisting he is the hardest member of the Jonas family to impress: "He'll tell it straight up, and he'll be mean if he needs to. He's a good critic. He's a mini Simon Cowell."
