While chatting with the magazine, Jenna reflected on being on the set of Step Up over ten years ago, where she and Channing first locked eyes. She says she originally told her co-star he probably wasn't ready to jump into another relationship, but that all changed after a late night of partying.
"It was two nights of being weird. We hadn't even kissed," Jenna remembers. "And then he went out partying with a bunch of dancers. His room was right above mine, and he came down drunk with a sombrero on, banging on my door."
"He was like, 'I couldn't stop thinking about you. Let's do this. I just want to be with you,'" she adds. "From that point forward, we were together."
Flash forward to present day, and the couple, who share 3-year-old daughter Everly, are happier than ever. Jenna reveals she and Channing "definitely have a very happy and healthy" sex life.
"I've always been a very sexual person," she confesses. "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," she continues. "He's very in tune with that."
As for parenthood? Jenna admits that's a completely different story!
In a behind-the-scenes interview clip obtained by ET from her photo shoot with Danskin in August, the brunette beauty opened up about raising a toddler.
