Jenna also showed off her fit bod at the Instyle Golden Globes after party in a black strapless Julien MacDonald gown. She brought her stylist, Brad Goreski, as her “hot date” for the night, documenting their antics on Snapchat.

Jenna recently got candid about the couple’s sex life in her cover story for Cosmopolitan.
"I've always been a very sexual person," she told the mag. "Something about being a dancer connects you to your physical body. It's primal, earthy, sexual energy by nature. You feel your body in a certain way. Channing is very much the same way. He's very in tune with that."
