Dallas Austin -- Justin Bieber Can Do ANYTHING He Wants in My Home

Mega record producer Dallas Austin just made it clear ... Justin Bieber can do ANYTHING he wants in Austin's Atlanta home ... ANYTHING.

We got Austin leaving Warwick nightclub in Hollywood Wednesday night ... and asked him about the story we broke earlier in the day ... that Bieber just rented Austin's ATL mansion for 3 months.

Listen carefully to the video. It sounds like Austin is open to selling Bieber the house and that Bieber's down with that.
