Between flashing her bra under a sheer shirt last week and trying out a trendy 'do at a gala event on Saturday, Reese Witherspoon seems to be experimenting with a sexier look right now.

And on Wednesday night the star continued to change it up when she hit the stage at the CMA Awards in Nashville rocking a hot pink strapless Stella McCartney dress with ruffle detail on the side. She wore her hair in loose waves and accessorized with nude pumps and sparkly Van Cleef & Arpels earrings.

The newly-married Tennessee native, 36, presented Blake Shelton with the award for Male Vocalist of the Year. See more pics of Reese and other stars at the CMAs.

Next up for the mom-of-two is coproducing a romantic comedy with Ryan Seacrest. The role will follow Witherspoon's buzzed-about turn in This Means War, set for a February 17 release.
