Shortly after getting kicked out of rehab and being ordered back into a 90-day live-in facility, Chris Brown has seen nothing but support from girlfriend Karrueche Tran.

According to HollywoodLife, on-again off-again girlfriend Karrueche Tran has not shied away from Chris Brown despite his legal and anger management troubles stemming from the 2009 Rihanna assault case.

"They were together afterwards and she held his hand when they walked out, and in the car ride home, he laid his head on her shoulder," says a source. "She thought he wanted to cry but Chris will never let anyone see him like that.

"Karrueche told him, 'Keep your head up and stop thinking about what everyone else is saying. Focus and get all this sh** done so you can put it all behind you. Don't worry, I'm here. She was hoping that would lift him up"

These are kind words given Chris Brown's struggles during rehab after smashing his mother's car window only 16 days into treatment.

And in all of this, Chris Brown seems forever entangled in his tragic mistake from the Rihanna assault incident four years ago, and some are wondering whether the singer will ever be able to move on from the past.

"[Chris'] really trying to move forward from the incident with Rihanna, but feels it's just going to haunt him for the rest of his life," says a source to RadarOnline.

Reportedly, Chris Brown has also been ordered to submit periodic drug testing by the court.

The question becomes, will girlfriend Karrueche Tran continue to stand by him if his situation worsens? Only time will tell if he will be able to go through the 90-day rehab treatment without further incidents.
