Why Jenna Dewan Is Stripping Down to Her Bra and Underwear

On Tuesday, Dewan Tatum teased her fans on Instagram by posting a sexy pic of her hot bod and wrote, "BTS of Tuesday. Find out why in the world I'm dressed like this on @CWNoTomorrow tonight #NoTomorrow.”

Jenna was referring to her guest-starring role on “No Tomorrow,” which has her taking on the part of a free-spirited woman who engages in a naked yoga session with lead character Xavier, played by Joshua Sasse.

Earlier this year, Jenna showed off her toned legs while rocking a bikini during a beach photo shoot in Malibu. As for how she keeps her body looking so toned and amazing, she told Natural Health, "After going vegan, I felt so much better. My skin cleared up, I had a ton more energy, and I just felt clearer in the head. I swear by a green smoothie every morning with spinach, romaine, kale, apples, and banana. I've gotten Chan into those, too!”

Along with eating healthy, Jenna also hits the gym with her stylist Brad Goreski, who recently invited her to Barry's Bootcamp West Hollywood for an event to benefit non-profit dog rescue, Dogs Without Borders.
