Selena’s brother, A.B. Quintanilla, tells TMZ he was moved when he saw Royalty‘s Halloween getup — a glitzy purple jumpsuit like the one Selena made famous in a 1995 Houston performance … just a lot smaller.
A.B. tells us, “I think it’s beautiful that of all the Disney characters, princess and superheroes, she picked my superhero.” He also gave props to Chris, saying … “you have an adorable daughter.”
He should’ve shouted out Nia Guzman — we’re told Chris’ baby mama chose the costume because Royalty was born in Corpus Christi … Selena’s hometown. Plus, Nia’s a huge fan.
We’re told celebrity designer, Robyn Thicck, put the outfit together.
