Nia Guzman "can’t say anything positive about" co-parenting with Chris Brown.

She said: "Well, the world didn’t find out about her until a year ago. He always knew about her, he just wasn’t ready to deal with the situation. But, it’s been quite the experience. I can’t say anything positive about it ... at all. Nothing positive."

The pair's feud escalated recently when Chris accused Nia of "sexualising" their daughter when she posted a photograph of Royalty on her way to ballet class in a tutu.

Referencing the incident, she said: "I mean the fact that I had just spoken with him. He had already seen a video of her on her way to ballet class. To make that remark online, was totally insane to me. Because I have a phone. I have a phone, and I tried over and over and over to co-parent, to try and get this right.

"She always dresses like that to dance class ... It was a funny moment, and she was leaned back looking at me because she was totally p**sed off, because it was time to go ... but she didn’t want to leave."

And Nia also hit back at claims she tried to get his access time reduced.

She told Latina magazine: "I didn’t go back to court to limit his time, at all ... What’s in place right now, his days that he gets her, was agreed upon ... It wasn’t court ordered or anything like that... all I wanted was a set nanny in place ... She’s only two, and she’s a lot of work. I just wanted a nanny in place when she was with him, and it be agreed upon."
