Matt Kemp Rihanna Engaged?

“Always a bridesmaid, never a bride…” is one old saying that has no place in Rihanna’s world.

The pop tart has been bitten by the marriage bug and is itching to rush slugger beau Matt Kemp to the altar after hosting a Sin City bachelorette party for engaged galpal Katy Perry earlier this month.

After all, the girls spent the night dancing with midgets and munching on a cake crafted in the shape of a penis. With all that debauchery and partying piled into one weekend — we’d get married just for the Hen Fest!

“Ri’s really involved with the wedding because she’s one of Katy’s best friends. She wants that same sort of happiness. They want a formal engagement next year and won’t take long to get married,” a mole in the “Umbrella” crooner’s camp yapped to London’s News of the World this week.

“Rihanna adores Matt. She can’t imagine life without him.”
