Chris Brown has been sentenced to 90 days in rehab but it turns out he's not going to go anytime soon. A source told Hollywood Life:

"[Chris] doesn't have to go right away to rehab but he'll have to commit real soon," a source close to the "Fine China" singer told HollywoodLife.com exclusively. "I know he wants to be home and spend thanksgiving with [his on-again/off-again girlfriend Karrueche Tran] and his family so we shall see."

Chris got lucky at court that he just was sent to rehab and not to jail -- but he doesn't look at it that way.

"He's not relieved because he knows the situation isn't over. He still has to go back to court. He knows he's got a long way to go and this is just the first step," a source told us. "He's lost all of his belief in the system and even though he gets to go home, he knows they're still after him."
