CHRIS BROWN BABY ROYALTY REALLY DIGS ME!

Chris Brown has a new #1 fan and she's Royalty.

You gotta see this video. The 9-month-old baby girl is transfixed with Chris' hit song, "New Flame."

Royalty's maternal grandma handed the kid an iPhone and played the tune, and it's as if the little girl knows what's up.

Pretty adorable.
