Justin Bieber's pals just need somebody to love someplace to party?

Justin's buddies threw a massive shindig at his Calabasas mansion last week, with lots of people smoking pot and getting drunk, according to TMZ.

The Biebs was out of town on his European tour, but that didn't stop his buddies — including rapper Lil Twist — from inviting tons of people over on March 19, including 40 girls.

People were allegedly smoking pot at the party, and photos from the festivities show dozens of beer bottles, along with some liquor bottles, too.

Don't you hate it when your friends throw a big party at your house when you're not there?
