Their debut single went to number one and they're followed by screaming girls wherever they go, but McFly say they're just a bunch of normal lads.
"I suppose we get recognised a bit more, but we don't go to any celebrity bashes," McFly told Newsround Online.
"We're just your average teenage boys, but playing in a band."
"It's so weird with the screaming girls because there are loads of better-looking boys." McFly's second single, Obviously, is out on 21 June.
