Nia Guzman, the mother of Chris Brown's daughter Royalty, reportedly lashed out at the R&B singer claiming that he spends more on cars then he does on their baby.

The whole controversy actually started when Chris Brown ranted on Twitter accusing his baby mama of using Royalty for her own selfish needs.

On Aug. 6, he wrote, "Some men my age run from their responsibility as fathers. I embrace mine. Just sucks that some females use children as meal tickets."

Three minutes later, he followed the post up with another tweet probably aimed at his baby mama, "Using a child as leverage is never ok. The highest praise to the men who actually want their kids."

One fan called Chris Brown out by commenting, "So, you're rich and you're upset that you have to put out more than the average Joe because you had a baby by an average Jane?"

Another gave some advice, "Nia just wants 2 have 2 deal with u more she is stoked that she is ur baby mama Get the legal stuff handled so u can njoy ur kid."

But Chris Brown's baby mama is not about to go down without a fight.

A source told Hollywood Life that Nia Guzman was livid about the accusation she was only using Royalty as a "Meal ticket."

"Nia just wants her daughter to be set for life and doesn't think she's being unrealistic in what she wants from him monetarily," the source alleged. "Maybe if Royalty was a car, Chris would have already written a check for several million dollars."

"That's the type of stuff Nia's disgusted with. He will drop millions on cars, rims, tires, Jordan sneakers - all that fabulous crap - but won't make sure Royalty's living in the lap of luxury. That part, that part right there, drives Nia crazy."
