Robert Griffin III went straight from the altar to the beach with his new wife for a little volleyball ... and a major love tap.
Newlyweds RGIII and Grete Sadeiko hit up Miami Beach Sunday a day after tying the knot in town. They seemed to be kickin' ass as a team on the sand ... Grete was showing off a lot of ass, too, which didn't go unnoticed by her NFL star hubby.
This is RG's second marriage. Grete gave birth to their daughter last summer -- he's got another kid with his ex-wife, Rebecca Liddicoat.
