The Washington Wizards baller and former 'Love & Hip Hop' star have been dating for over a year now ... and announced earlier this month they were expecting a little bundle of joy together.

Adams is 8 months preggo ... and revealed they're having a baby boy!!

K.A. posted several pics in her birthday suit for the big announcement ... and sent a message to their future son -- "Mommy & Daddy can’t wait to hold you. We already love you more than you can imagine!"

Bradley added a message of his own, saying "@kamiahadams and I promise to love you, protect you, teach you, support you, respect you, and be the best parents we can possibly be!"

Congrats!!
