Mia Khalifa says she loooooves Houston Texans rookie Deshaun Watson ... but insists it's strictly platonic.
The ex-porn star wished the QB a happy 22nd birthday Thursday with a video of them playing mini basketball in her apartment this past June ... leaving people speculating whether they were a "thing."
Happy birthday, @deshaunwatson! For the record, I let u block that dunk cause ur a rookie and I didn't wanna risk hurting you before game 1 pic.twitter.com/AdS42yZ7hj
