He fathered a child with another woman during their relationship so it is no surprise that Karrueche Tran's friends were far from pleased when her ex-boyfriend Chris Brown joined them at a Los Angeles nightclub.
Tran, 27, partied at Hollywood's Playhouse on 4 June where her close friend Christina Milian was hosting an event and, surprisingly, her ex-boyfriend showed up to attend the same event.
The Loyal singer appeared keen to make contact with the model as TMZ footage shows Brown following his ex out of the venue.
In one of the clips, the aspiring actress seems keen to distance herself from her former beau, who nudged her friends out of the way so he could sit next to Tran in the car.
At one point, the Ayo hitmaker can even be heard shouting: "Move to the back," to which a friend of the model's replies: "Get out the car!"
Brown, 26, ignored the request and he can be seen sitting right beside Tran as the car pulls away.
According to the website, the Grammy-winner was dropped off at his house however the drama was not over as he is said to have visited Tran's home at around 3:30am, allegedly banging and screaming.
The model reportedly agreed to speak to the singer in a public place, but their conversation at Norm's Diner is said to have escalated into an argument with TMZ describing it as a "full-blown shouting match".
The reunion will come as a surprise to most as it was only two months ago that the model tweeted she was done with the R&B star after it emerged he had fathered one-year-old daughter Royalty with another woman.
Following her public tweet, Tran then appeared in an episode of Iyanla Vanzant's Fix My Life where she broke down in tears over the singer's mistreatment of her throughout their five-year relationship, which included breaking up with Tran to reconcile with his ex-girlfriend Rihanna.
In an interview with Real 92.3's Big Boy In The Neighbourhood, Tran opened up about their split, telling the radio host: "When [the baby news] hit TMZ I was like: 'Oh, ok.' I called him, I cussed him out and I was like [wipes hands].
"Because after the whole Rihanna thing it been like a year or whatever where we've been trying to fix what was broken and that was just the icing on the cake so I just had to completely pull away."
In May, Brown was embroiled in a social media feud with model Tyson Beckford after the Britain & Ireland's Next Top Model judge was pictured with Tran over Memorial Day Weekend.
