Is Chris Brown the Real Father of the Baby? Ex Girlfriend Rihanna Shocked

In what sounds like a love triangle, a man has claimed that he thought he was the father of the 9-month-old baby girl and was left devastated on learning singer Chris Brown fathered her.

A man has claimed in an Instagram message to @BallerAlert that he thought he was the real father of the baby and expressed his displeasure over reports that she is Chris Brown's daughter, according to a report by Hollywood Life. 

"The Saddest Day Of My Life This lil girl meant the world To Me," wrote the alleged father of the baby on Instagram. "I been There Through Everything I was told This Was My child How Can This Be happening A Man Just Steps in and Take Over What I Built What I lived for I Dedicated My Whole Life To This Family Now Everything Is Gone..," the caption reads. "@tmz_tv @balleralert Y Did this happen To me Now I lost My Lil Girl For Good." 

However, the unidentified man has deleted his Instagram account after posting the controversial message. 

In an exclusive report, TMZ claimed on Tuesday that Chris Brown is a father of a 9-month-old baby girl and that a 31-year-old former model named Nia is the mother of the child. Sources connected to the duo said that "Chris is happy about being a father" and on very good terms with the mother of his child. 

The report went on to say that a formal child support order might not be in place and that the baby looks more like Chris Brown than her mother.

Meanwhile, Hollywood Life has claimed in an exclusive report that Rihanna, 27, is shocked to learn the news of his ex boyfriend's child.

"Rihanna is shocked and had to read the reports four times before it finally sunk in," an insider told Hollywood Life. "But first things first, and that's that if it's true, Chris will be a good father and take care of his little girl."
