Chris Brown and Karrueche Tran split again - report

R&B star Chris Brown has reportedly split from his on/off girlfriend Karrueche Tran once again, just weeks after reuniting following his two-month stint behind bars.

The Kiss Kiss hitmaker walked free from jail on 2 June (14) after admitting to breaking the terms of his 2009 probation by getting kicked out of a court-ordered rehab program.

Tran celebrated his release by throwing him a star-studded surprise party and she accompanied her beau as his date to the BET Awards in Los Angeles on 29 June (14).

They spent Independence Day holiday together on Friday (04Jul14), when Brown uploaded a raunchy snap of Tran lying face down on a bed wearing nothing but a bra and a skimpy thong, baring her backside, to his more than 3.7 million followers.

However, it appears their romance has since soured, prompting both Brown and Tran to delete all photos of the couple from its Instagram.com accounts and 'unfollow' one another.

Tran hinted at the break-up on Sunday (06Jul14) with a cryptic post that read: "Love what you have before life teaches you to love what you lost".

She followed it up with a Buddha quote which stated, "In the end, only three things matter: how much you loved, how gently you lived, and how gracefully you let go of things not meant for you." In the accompanying caption, she simply wrote, "Well.."

The former couple began dating in 2011, two years after Brown was convicted of assaulting his then-girlfriend Rihanna on the eve of the Grammy Awards in 2009.

He and Tran split in 2012 as he attempted to rekindle his relationship with the Umbrella beauty, but he reconciled with the model in 2013. They parted ways again in early March (14), only to pick their romance back up weeks later.
