Karrueche Tran has reached her breaking point. The model -- who has been on-and-off with Chris Brown for years -- officially dumped the controversial singer after finding out that he reportedly fathered a nine-month-old baby girl.

Tran tweeted her stance on the situation today (March 4), writing, in no uncertain terms, that she is not down with any "baby mama drama" and is leaving the "Autumn Leaves" singer.

After posting the tweet, Karrueche's name immediately began trending on Twitter. Her tweet also seemed to confirm the news about Brown's paternity.

As we previously reported, TMZ claims that Brown is the father of a nine-month-old baby girl. The baby's mother is allegedly a 31-year-old model named Nia, whom Brown has known for years. The site reports that Brown is happy about his alleged paternity.

We can see, however, exactly why it is that Karrueche Tran is not. Whether or not the singer helped to conceive the baby when he and Tran were on one of their many breaks, the situation is undoubtedly messy and we can understand why the model does not wish to be involved in it. While Karrueche Tran has previously stuck it out in such turmoil like a love triangle with Rihanna, Brown's numerous arrests and his time spent in both rehab and jail, it looks like news of his alleged fatherhood was just one red flag too many.
