brooklyn decker jennifer aniston Bikini battle: Jennifer Aniston vs. SI swimsuit model Brooklyn DeckerWould you want to be in a bikini next to a Sports Illustrated Swimsuit issue model?

Not just any swimsuit model, mind you. Just the fairest-of-them-all chosen babe who needs no retouching and gets to grace the coveted cover? Did we add that the swimsuit model is  5’9″, only 23, reminds almost everyone of a young(er) Elin Nordegren and you’re say, 41.

Not exactly a thrilling prospect, right?

]]>Well, Jennifer Aniston feels the same way about working with SI cover girl Brooklyn Decker — who thank God is married to tennis star Andy Roddick — in their new movie, “Just Go For It.” So Jen’s reportedly having her gym equipment shipped over to the set in Hawaii. “Jen has been getting really wound up with the wardrobe department because her costumes are so skimpy and she’s worried about working with a younger model with a hot body,” a source tells The Daily Mail. “She has upped her fitness regimen and has had her gym equipment sent to her villa.”
Can you blame her? We sure don’t. Not that Jen is any slouch in the fitness department. She looks amazing thanks to a great diet, a personal friend yoga guru whom she sees five days a week and a regimen of Chinese martial arts and lots of cardio. Jen, we feel your pain. We’ll do some crunches and lunges in your honor tomorrow. Follow Zap2it on Twitter and Zap2it on Facebook for the latest TV, movie and celebrity news.
