After nearly a year of dating, LaMelo Ball and his girlfriend, Ana Montana, went Instagram official on Friday ... and things appear to be serious -- 'cause the model says she's in love!!
The Charlotte Hornets star and influencer certainly haven't been hiding their romance ... exchanging mushy social media messages and featuring each other on their stories over the past few months.
While everyone assumed they were the real deal, the two never really came out and confirmed they were "official" until Friday .
