Chris Brown threw shade at girlfriend Karrueche Tran but the model is not about to back down from the "X" singer either in the latest saga about the on-and-off couple.

In an MTV piece, it was confirmed that Karrueche Tran is no longer a girlfriend of Chris Brown as he launched a tirade during a recent performance at Cali Christmas for Power 106 last Friday.

"How many single ladies we got in here tonight?" Chris Brown asked the crowd prior to singing "Loyal." "Well, I'm single, too. F- that b--."

His shade apparently reached the model's ears as she posted on Twitter shortly after: "Niggas be in they feelings when you break up with them lol."

During the night, Chris Brown spent time with Khloe Kardashian, Kendall Jenner-who was sitting on the singer's lap-and Kylie Jenner and they even posed together for an Instagram photo.

Kendall Jenner was earlier reported to be crushing on Chris Brown. A report from Us Weekly alleged that the rising model has become infatuated with Karrueche Tran's ex boyfriend.

Reportedly, Kendall Jenner partied with Chris Brown and his friends following the MTV Video Music Awards at his place. "They hung out with friends until 5 a.m.," a source told the magazine.

"Other performers at the 2014 Cali Christmas concert included rapper T.I. and fellow hip hop artist French Montana, Kardashian's ex," said E! News. "It is unclear if the two interacted at the event. The two recently broke up for the second time after dating on and off for the past few months."

Chris Brown also posted a rant on Instagram against girlfriend Karruehe Tran as he wrote: "We've got scars. Some of them u gave me, some of them I've caused. That ride or die act we have been fooling the world with obviously ain't working. I was locked up for damn near 4 months and only got 1 visit from you while u was hosting parties and taking secret trips to Toronto, going on dates with Drake!

"All these celebrities ****** ain't **** and only focus on themselves. 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.

"So let's not try to save face for public opinion because I don't need to play victim so people can take my side. So miss me wit the ******. Now yall know the real."

Just several months back, Chris Brown and Karrueche Tran were rumored to be pregnant with their first baby together.
