What are friends for if not to wreck your cars and cash in on your fame? That's right, Justin Bieber "pals" Lil Twist and Lil Za are trying to sell a reality show focusing on their lives to MTV -- and no doubt using their superstar connection to help do it!

Hmm ... wonder if this latest piece of news is yet another reason why Justin's manager Scooter Braun wants the troublesome Lils out of Biebs' Calabasas, Calif., mansion!

The Bieber hangers-on aren't hiding the information, though, with Za openly telling TMZ: "Twist is actually about to pitch a TV show with MTV ... Hopefully they pick it up. They will though ... it's quite entertaining."

Za, who's trying to break into acting while Twist works on his music career, reveals that Justin would appear on the proposed show "here and there," when he's not out on tour.

Do you think Justin knows about this yet, or will this finally be last straw in the trio's toxic relationship?
