American recording artist and actor Chris Brown's daughter's mother, Nia Guzman Amey does not want Karrueche Tran to spoil her toddler with gifts.

According to Hollywood Life, Amey feels the 26-year-old model would be crossing the line if she continues to pamper Royalty with lavish gifts.

"Small gifts here and there and on special occasions are cute, but Karrueche would be out of line if she were buying Royalty a lot of expensive things, like clothes and toys, on a regular basis. That's Nia's job, not Karrueche's," a source said.

"Nia's like whatever when it comes to Karrueche. The only relationship she and Chris have revolves around their daughter. Chris is not her man. He can do whatever it is he wants to do," another insider told the website. "Royalty absolutely knows who her mother is and that's Nia! As long as Karrueche knows her place and is respectful when she's around their daughter, Nia's cool with that."

"She would hope that Karrueche has enough decency and respect to stay in her lane and not try to outshine her. That would be grounds for a serious conversation, if she crossed the line." the source added.

After reports emerged about the Say Goodbye singer's love child, Tran announced her split with Brown by declaring she did not want "baby drama".

Later, Tran opened up about their latest break-up in an emotionally-charged interview with Fix My Life coach Iyanla Vanzant, which aired on Oprah Winfrey's OWN network.
