Brooklyn Decker models lingerie and crushes on Gisele Bundchen. Hey there, I'm Karli Bulnes. We take you behind-the-scenes of her hot GQ shoot in today's PopSugar Rush.

Brooklyn Decker seriously steams up the screen in this backstage footage of her GQ photo spread. The 25-year-old strips down to simple yet sexy lingerie, even sporting a sheer top and tiny shorts in one of the images that made it into the May issue of the magazine.

Brooklyn's been happily married for the past three years to tennis pro Andy Roddick, though she admits to having a bit of a crush on someone else ...fellow model Gisele Bundchen.

Brooklyn tells the mag, [pull quote] 'I have a top-five list, and Gisele is my number one. So she can do no wrong in my eyes . . . Gisele is just so perfect in every way.'

Girl crush aside, Brooklyn also talked about her upcoming big screen projects - she scored parts in Battleship and What to Expect When You're Expecting, which both hit theaters on May 18th.

Before then, you can catch Brooklyn when the May issue of GQ hits newsstands April 24th..
