It's about time! Justin Bieber's manager Scooter Braun has had enough.

Braun wants those hangers-on known as Lil Twist and Lil Za out of The Biebs' mansion in Calabasas, Calif., the scene of many of The Biebs' neighborly headaches as of late. They've been living there and making a big ol'mess for Biebs, which also means it's a big ol' mess for Braun. He is dunzo with their antics.

"Lil Twist and Lil Za have basically been ordered by Scooter to vacate Justin’s house," an insider with knowledge of the situation told Radar Online. All we can say is FINALLY! Someone had to step in and amend this situation because where there's Twist and Za, there's headaches and bad publicity.

The source said, "He wants them out by the end of the month and they’ve even already been set up with their own apartments." Hey, at least they are not being tossed out on the streets, right?

Braun's job is to protect The Biebs in all facets and he realizes that his pals are nothing but trouble. "There’s a growing disenchantment with them," the source said.

Again, we thought Braun should have intervened sooner, but better later than never (say never).
