Jenna Dewan wasn't about to let things heat up between her and her hunky co-star, Channing Tatum, on the set of the 2006 feature film "Step Up."

But then Tatum showed up at her hotel room door drunk and wearing a sombrero, and, well, all bets were off.

Dewan — now Dewan Tatum — is the cover star of Cosmopolitan's January 2017 issue, and inside the magazine she opens up about the early days of the couple's red-hot romance.

"It was two nights of being weird. We hadn't even kissed," said the 36-year-old dancer-actress, who revealed that she had just split with a boyfriend and told Tatum she wasn't ready for another.

"And then he went out partying with a bunch of dancers," she continued. "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,'" said Dewan Tatum. "From that point forward, we were together."

One secret to their decade-long romance? Plenty of good lovin.'

"We definitely have a very happy and healthy (sex life)," Dewan revealed to Cosmo. "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 said. "He’s very in tune with that."
