But Chris felt his baby mama was using the Guzman love-child for money. Brown tweeted, "some females use children as meal tickets" Perez Hilton reported.

Chris Brown and Royalty look stunning on Instagram but the singer-songwriter is not happy.The Loyal singer's online venting rant follows a move by Guzman to limit Brown's visitation rights to just supervised ones. But the 26-year-old is filing for joint custody of the Nia Guzman Chris Brown baby and getting rid of the part about the supervised visits.

Here's what Chris had to say about Royalty's mama on Twitter: "Some men my age run from their responsibility as fathers, Eonline shared. "I embrace mine. Just sucks that some females use children as meal tickets." He added, "Using a child as leverage is never ok. The highest praise to the men who actually want their kids."

"The "Forever" singer often shares pictures of his daughter, calling her the "best thing" in his life in addition to referring to her as Queen Royalty," E reported. "Although the cordial relationship between Guzman and Brown seems to have deteriorated, at one time they were getting along nicely for the sake of their daughter."

When Chris stopped paying Royalty's child support, Nia upped her request to $15,000 a month. However, a judge has yet to rule on this. But Nia Guzman Chris Brown baby mama was apparently upset at the time over gifts that the singer bought his daughter - like model vintage cars.

She was also furious that Chris didn't show up for Royalty's birthday party. The "No Air" performer offered to pay for tickets to Disneyland to make up for his oversight, but Guzman decided to request for more child support instead.
