GloRilla may have found herself a baller ... she and NBA star Brandon Ingram were seen getting close at a Cabo nightclub -- and left together in the wee hours of the morning.
In new footage -- obtained by TMZ -- the rapper is seen all over the Toronto Raptor ... wrapping her arms around his neck as they swayed together on the dance floor early Monday morning.
We're told GloRilla was celebrating her birthday -- which is today -- at a nightclub called Balam .
