Chris Brown – Baby Mama Nixed Fab Disney World Birthday for Royalty

Chris Brown offered to fly his daughter Royalty and the kid's mom to the happiest place for her first birthday, but his baby mama shut down the offer.

Brown's rep tells TMZ, it's true he was a no show for Royalty's 1st birthday, but it's because he was shooting a music video in Miami. The rep says, "Like any working parent, Chris is doing his best to prioritize the needs of his daughter."

But Chris had a plan ... flying "the entire family" to Disney World. It's unclear if that included King Ba, Nia Guzman's BF who has been trying to assume the role of Dad. But Chris insists Nia turned him down flat.

Nia's pissed that Chris didn't show for the shindig at Chuck E. Cheese's in Houston, but Chris says he'll throw a special party for Royalty the next time he sees her.
