The troublesome apple doesn't fall far from the irresponsible tree.
So Joe Jonas tells Scene Magazine this month when asked about Justin Bieber and why that young singer has been acting like such a spoiled brat over the past few months.
"I think we all saw it coming," says of Bieber's downfall, which has been lowlighted by an arrest for DUI and a deposition that paints the singer as the world's most arrogant A-Hole.
And just what made Jonas so sure Bieber would fall apart?
"Your dad is your party animal - that's going to sum it up pretty quick," Joe said. "There's an equation for some sort of explosion."
How very true.
Jeremy Bieber and his son notoriously got crazy high during a private flight to the Super Bowl in February, doing a lot of marijuana together and being extremely abusive to flight attendants on board.
Jones does admit in the interview that he had it easier than Justin and that Bieber is under a much bigger "microscope" than he and his brothers were during their time in the spotlight.
But that excuse only goes so far.
"[Bieber] is having a very tough time finding balance," Joe said in the understatement of the year.
Let's all hope Justin locates said balance before his next arrest proceeds a far more dangerous outcome.
