Brooklyn Decker: The Wiener, the Bun and the Boob

Tennis fans will recognize Brooklyn Decker as tennis champ Andy Roddick's gorgeous wife — she's in his box all the time!

The 22-year-old Sports Illustrated swimsuit model is making a cameo on the hit ABC show Ugly Betty next week (October 30 @ 8PM ET/PT).

Here's a synopsis of the ep: Betty (America Ferrera)is overwhelmed with her editorial work, so Wilhemina assigns Marc (Michael Urie) to be Betty's temporary assistant. Betty's story idea to cover the worst jobs in New York goes south when she has to dress up as a hot dog and do a Bollywood dance number. Meanwhile, Marc frets that he'll never be taken seriously by his idol at Vogue magazine, Hilda gets Archie's campaign in trouble, Daniel (Eric Mabius) hires a gorgeous but inept assistant (Decker), and Natalie introduces Daniel to the Community — a group whose charismatic leader (Dylan Baker) zeroes in on Daniel.

FYI: Brooklyn is wearing the fierce pair of Brian Atwood Wicked' shoe in purple suede (as worn by Katy Perry and Jessica Stroup).
