Joe Jonas Slams Justin Bieber, Calls His Dad A "Party Animal"

Joe Jonas appears in the April issue of Scene magazine, and the 24-year-old musician totally throws Justin Bieber (and his dad Jeremy) under the bus. We gotta wonder how much of this is coming from Joe being jealous of the Biebs ... after all, Joe is worth an estimated $18 million while Bieber is worth at least $130 mil.

"I’ve had an easier route than most," Joe tells the mag. "The youngsters just turning 20, the Biebers of the world, are under a microscope." Did he stop and think that maybe this is because Bieber is um, at least ten times bigger than the Jonas Brothers were back in the day?

"[Bieber] is having a very tough time finding balance," he continued. "I think we all saw it coming. Your dad is your party animal -- that’s going to sum it up pretty quick. There’s an equation for some sort of explosion." While we do agree with that statement, we can't imagine what Bieber is going to say when he finds out Joe is talking smack about his family!

And this isn't the first time Joe has taken a jab at Justin! Last summer when he chatted with MuchMusic, Jonas referenced some of Bieber's bad behavior and said, "We never really had the interest in doing things like peeing in buckets or anything like that. We try to be careful."

Remember when Joe dragged Demi Lovato and Miley Cyrus' names into the mix and suggested that they were the ones who pressured him into smoking pot? It certainly seems like he likes to stir the pot ... either that, or he's got something to promote!
