Chris Brown calls on/off girlfriend Karrueche Tran from Men's Central Jail to tell her he loves her

He's currently in solitary confinement at the notorious Men's Central Jail in downtown Los Angeles.

But Chris Brown left a cheery voicemail for on/off girlfriend Karrueche Tran on Monday night, which she shared with Team Breezy.

'Just calling all my fans. Y'all know I love y'all,' the incarcerated crooner - who turns 25 next month - was heard saying.

'Thank y'all for the support. Thank you for everything. You know, the Loyal video came out so I hope y'all enjoy that. And most importantly, K...Karrueche, I love you. So thank you.'

The half-Vietnamese model - who turns 26 next month - was previously rumoured to have broken up with her bad-boy beau while he was in an anger management rehab facility.

Chris will remain behind bars until he goes on trial April 23 for allegedly breaking a man's nose at the W Hotel in Washington D.C. last October.

At the time he and his bodyguard were arrested, the Grammy winner was still on probation for brutally attacking pop diva Rihanna in 2009.

RCA Records will release Brown's double-disc sixth studio album X on his 25th birthday - May 5.

The Sex You Up singer is next scheduled to perform May 9 at California's Sleep Train Amphitheatre in Chula Vista.

Meanwhile on Friday, Karrueche will host a party with America's Next Top Model contestant Don Benjamin at Studio 8 in San Jose.
