Miley Cyrus is giving Justin Bieber behavior tips?! Well -- now we've heard it all!

While making an appearance on The Tonight Show with Jay Leno on Thursday night, the 21-year-old twerker gave the Biebs a piece of advice on how to stay out of trouble.

"You've got a lot of money. Pay people to make sure you don't get in trouble and party at your house," said the hard-partying star. "Buy a house, and add a club to it."

Sounds like some sound advice actually! While we all know Miley loves to party like a rockstar -- she's yet to have any problems with Johnny Law. There may be some validity to her house party pad idea -- since it doesn't look Bieber is going to slow down any time soon despite his recent troubles.

Last week, the "boyfriend" singer was arrested and charged with DUI, resisting arrest and driving with an expired license in Miami, FL. Just Wednesday, the Canadian cutie turned himself in to authorities in connection with an alleged assault involving a limo driver in Toronto last December.
