Joel Embiid is taking ANOTHER shot at his celebrity crush — this time, professing his love in a video message to Rihanna … “I love you.”

Embiid’s been after Rihanna for a while … ever since she allegedly shot him down in 2014 and told him to come back when he’s an All-Star.

Well, he killed it this season and could win Rookie Of the Year … and clearly, he’s got the confidence to double down on his efforts to court the pop star.

Still, Embiid’s staying humble … and told our photog, it’s his 76ers teammate, Dario Saric, who should get R.O.Y.
