Update 7:10 p.m. EST: The full name of the mother of Chris Brown's alleged baby has been revealed as Nia Gonzalez. She is a friend of singer Christina Milian, the Heavy wrote.

Original story:

Chris Brown’s on-again, off-again girlfriend Karrueche Tran seemed to confirm rumors about him being the father of a 9-month-old girl. Now many are begging to know, who is Nia?

Not much is known about the mother of Brown’s child. Her last name hasn’t even been revealed. TMZ, which broke the story, wrote that she’s a 31-year-old former model. She and Brown are no longer romantically involved and do not have a formal custody agreement for the little girl, whose name wasn’t revealed either.

What the news site did share about Nia is that she hails from Texas and did some modeling, in addition to appearing in music videos. She made a semi-nude appearance in Phil Wade’s “Dreams of You” video.

Tran, 25, took to Twitter to break up with Brown after she heard the news. She and Brown are known to air their dirty laundry on social media, so it’s not surprising that she posted a tweet to let everyone know she and the R&B star were done. “Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me,” she said.

Tran and Brown became involved in late 2011 after he and Rihanna split up. Since then, he has gone back and forth between the two women and also apparently hooked up with Nia in between. To make things worse for Tran, she apparently partied with Nia in Las Vegas in May 2013, TMZ wrote. The site unearthed an Instagram picture that show Tran, Brown and Nia in the same picture. Nia apparently got pregnant that summer.

Tran isn’t the only one who is heartbroken. The man who thought he was the father of the baby girl broke down on Instagram, Hollywood Life wrote. Considering the user tagged TMZ in the message, it could just be a hoax, though.

Brown has not commented on his alleged love child, but he hasn’t stayed entirely quiet, either. He posted several pictures to Instagram Wednesday, ignoring the rumors and the fact that his girlfriend broke up with him on Twitter.
