If these two don't make it official soon, then we don't know WHAT'S up!

Rihanna joined Drake on stage Saturday night at his LA gig and the rapper AGAIN professed his love for the sexy chanteuse, saying, "LA, I pray that you find somebody that holds you down like this woman right here."

These two are like the Brad and Angelina of hip-hop! You can't get bigger and better than these two -- put a ring on it already, Drake!
