The Loyal singer has been romantically liked to model Karrueche for the past four years. However the pair's relationship has always been rocky, and the pair have frequently split before reuniting. The pair were seen together last month, hand in hand at New York Fashion Week. But back in December, Chris launched a lengthy attack on his girlfriend via Instagram. Out and about: Karrueche, 26, was seen out with a friend in Studio City on Monday night . After pulling her up on only visiting him once during his four months in prison, he then accused her of 'going on dates with Drake'. He added: 'I made it clear to the world who my girl was and and made your life equal to mine even at the cost of me not focusing on my career at times. 'When this relationship first started u knew what it was and even participated in threesomes. I slowed all that s*** down.' Before dating Karrueche, Chris was in a relationship with singer Rihanna who he started dating in 2008. On February 8, 2009, an argument in the Deuces singer's car ended with a physical altercation that left the then-20-year-old Bajan beauty hospitalised with multiple contusions to her face. Chris, then just 19, turned himself in to police, where he was booked under suspicion of making criminal threats. He was charged with felony assault and making criminal threats, before pleading not guilty at his arraignment. Forgiven: Chris was involved with singer Rihanna before his romance with Karreuche. They started dating in 2008, split in 2009 and briefly reunited in late 2012. They're seen at the 2013 Grammy Awards . On June 22, 2009, the star pleaded guilty to a felony and accepted a plea deal of community labor, five years' formal probation, and domestic violence counseling. Chris started dating model Karreuche in 2011 before splitting up in late 2012 when he became romantically involved with Riri again. After the couple split in May 2013, Chris resumed his relationship with Karreuche.
