Ever since their nasty break up in February 2015, Chris Brown and Karrueche Tran have hardly met in same venue and even when they did, it never ended well.

The former couple showed up at the iHeartRadio Music Awards on Sunday night, April 3 but not together!

According to reports, the 'Loyal' singer was the first to arrive on the red carpet wearing anall-white look and dark shades as she posed for the photographers. His ex, Karrueche arrived later donning a red mini dress while rocking a lovely ponytail.

The pair has been on and off social media war recently. In a since deleted Instagram post, Brown blasted the model's acting career and new-found fame.

"I wish u the most successful career ever,” Brown, 26, wrote. “But I promise you this, once this ‘TALENT’ you have starts to simmer, so will everyone else including [Manager] Jacob [York], all of your famous friends know u how? How? How? How? How? .. Ok. So to end this petty game that’s gonna allow u to book more club appearances and ‘MOVIES’ that go straight to DVD I’ll leave you this [heart emoji]!”

In her response, Tran fired back saying: "You’re calling me a bitch yet you’re screaming my name in a song about getting back together? CAN ALL THIS PETTY S—T STOP. IT IS SO UNNECESSARY. You have a beautiful daughter and so much to live for. LIVE YOUR LIFE and be positive. I am so over the drama!"

We believe their management teams made sure both stars didn’t see eye-to-eye.
