*Karrueche Tran has reportedly vowed to support her on/off boyfriend Chris Brown after he was ordered back to rehab this week for an additional 90-day stint.

The model was spotted at a Los Angeles court earlier this week to hear a progress report on his probation, when the singer was told he must return to a rehab facility for a further three months, for throwing a rock through his mother’s car — just one week after he left another rehab center following a 16-day stay.

According to HollywoodLife, Karrueche was by his side holding his hand during the court appearance and is said to have vowed to help him through his drama.

“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,” a source the website. “She thought he wanted to cry but Chris will never let anyone see him like that.”

The insider continued: “Karrueche told him, ‘Keep your head up and stop thinking about what everyone else is saying. Focus and get all this s**t done so you can put it all behind you. Don’t worry, I’m here,’ She was hoping that would lift him up.”

Meanwhile, another source has told HollywoodLife that Chris, 24, is considering a move out of the Hollywood Hills on the advice of Karrueche, 25.

“When Chris was in rehab and Kae was living at his house cleaning it up, she found a lot of different stuff. Nothing bad – just cigarettes out by the pool, junk food like chips and such in the garage, a lot of liquor and all that,” a source told the publication.

“She told him how it felt like a party house,” the source added.

“He’s looking everywhere, but he’s not trying to be in the Hills. He wants to be in a less snooty area, where people are more accepting and cultured. He loves Venice and Marina Del Rey, and likes the energy Venice gives.”
