What the world needs now is love, and that’s just what Lizzy Caplan is reminding us in the new promo for her Showtime series Masters of Sex.

Caplan and Michael Sheen return this July for the third season of the show, which dramatizes the story of real-life 1960s sex researchers William Masters and Virginia Johnson. The promo recaps the show’s first two seasons, intercut with footage of Caplan performing the Hal David/Burt Bacharach hit.

Though the actress has stripped down and performed sex scenes for the racy Showtime drama, she told ET that singing on the show is actually more intimidating.

"I’m not a singer so it’s strange, but it’s fun," Caplan said. "I really enjoy doing it but I have to say that it is the thing that throws me out of my comfort zone far more than any nude scene."

Caplan already showcased her impressive pipes in a season one episode of Masters of Sex. See her perform "You Don’t Know Me," a 1960s hit popularized by Ray Charles, in the clip below.

The third season of Masters of Sex premieres July 12 on Showtime.
