Things got pretty intense last week after Tyson Beckford posted a selfie with Chris Brown's ex-girlfriend Karrueche Tran.

Let's just say there were a ton of slurry threats tossed around the Twittersphere that day, and although no actual blows were thrown, the message was clear: Chris Brown doesn't like it when his ex-girlfriend takes pictures with other hunky men.

But that's not going to stop her.

Tran told TMZ "I can do whatever I f---ing want to do," on Saturday night, despite her ex's overt jealousy.

When asked about the cause of all his upset, she said simply, "you're asking the wrong person, boo."

For his part, Brown, who ended up appearing at the same IHeartRadio event in Las Vegas on Saturday (May 30) as Beckford, did sort of apologized on Twitter for getting so heated about the sight of Tyson with Kerrueche.

"No drama!" he wrote. "People are really starting to make this sh-t an issue. I can be a real one and say that I was wrong for even pressing an issue ... I can be a man about it."

Brown later went on to write an expository open letter in which he seemed to admit his fault in his break-up with Tran (which happened after she found out he'd fathered a child with another woman while they were together).

In part, he wrote, "Most of my issues always deal with love and me being in my feelings. Not to mention me being a dog sometimes. I can’t speak for everyone but I can say that my actions contributed a lot to my karma."
