Which one is getting hitched?

No, it's not Stifler! Had to put his pic up since they remind me of each other so much...Tennis man Andy Roddick (top) is all ready to marry his gal Brooklyn Decker down in Texas this weekend ya'll.

The Austin wedding will be "very small. Just friends and family. Not a big Hollywood crowd as they're not like that," a source claims.

The couple met back in 07' when Roddick asked his agent to contact Brooklyn Decker's agent, after seeing her in Sports Illustrated. I want that one!
