Chris Brown -- Nia's Royal Baby Shower

EXCLUSIVE

Chris Brown's baby mama was treated like royalty at her baby shower ... and nothing says royalty like little Gucci boots and tiny Converse.  

We're told 40 friends and family of the former Texas model showered her with baby gifts last March at a Houston apartment banquet, hailing Royalty's imminent arrival.

The guest list included a guy named Brazil, whom she believed was Royalty's papa. He was zip-lipped during the entire soiree.

After gobbling down a crown topped cake, the ladies tested their mommy skills in a diaper changing contest. The winner was toasted with wine from baby bottles. Nia abstained ... something she clearly didn't do with Chris.
