Chris Brown just threw down a hip-hop papa challenge -- essentially putting Jay Z and Kanye West on notice ... that his baby girl is gunning for their daughters in the cute department.
It might seem like an odd way to mark Royalty's first birthday, but proud daddy Brown posted a 3-way split of Blue Ivy, North and his daughter.
Worth noting -- Chris put Royalty in the key center slot.
So, is he saying these are the cutest celeb babies out there? Or Royalty is THE cutest of them all?
By the way, Chris deleted the original post ... and added Wiz Khalifa's son Sebastian, and Tyga's son King -- so we're guessing this was just a big daddy shout out.
