Sports Illustrated covergirl Brooklyn Decker has joined the cast of the Jennifer Aniston and Nicole Kidman movie "Just Go with It," coming out Valentine's Day 2011.

The film stars Adam Sandler as a man trying woo Brooklyn, so he hires Aniston to pose as his fake estranged wife to help win Brooklyn over. Kidman's role is supposedly cameo-esque.
