On Tuesday night's show, the 35-year-old actress guest starred as a free-spirited woman who was quite flirty with Xavier Holliday (Joshua Sasse). While she's seen in the selfie wearing a black bra, underwear and a sheer coverup, Jenna stripped down for a naked yoga scene with the leading man.

ET called No Tomorrow one of the must-watch new shows of the fall and for good reason. The series follows Evie (Tori Anderson), a risk-averse quality-control assessor, who falls for the free-spirited thrill seeker, Xavier. However, Evie soon learns that Xavier has chosen to live his life this way because he believes the apocalypse is coming.

"This was a character where I pretty much said, 'I know this girl because I see so much of myself in her,' and that's what was exciting," Anderson told ET of her role. "No matter if she was being pulled in different directions, she still trusted herself and she made her own decisions. She's trepidatious. She's nervous. But at the end of the day, she's still her and she's happy being her."
