Jack Reynor and Rupert Friend, Strange Angel

Sex and rocket science are the twin engines fueling Strange Angel, the drama about real-life groundbreaking thinker Jack Parsons (Jack Reynor), who lived in L.A. before and during World War II. Jack only dreams of flight until he meets Ernest Donovan, played by Rupert Friend, a neighbor who becomes his guide into occult practices in which adherents of the unorthodox Aleister Crowley abandon every inhibition.

Together, they embark on a treacherous path as Ernest plays to Jack's unending curiosity. No doubt about it, this one's a scorcher.

Rose McIver and Rahul Kohli, iZombie

Ever since he first encountered not-exactly-living Liv Moore (Rose McIver), nerdy Seattle medical examiner Dr. Ravi Chakrabarti (Rahul Kohli) has been a constant platonic presence in her life (undeath?).

Alan Cumming and Bojana Novakovic, Instinct

Dylan Reinhart (Alan Cumming) is a brilliant former CIA operative working as a professor; Lizzie Needham (Bojana Novakovic) is the NYPD homicide detective who convinces him to join her in investigating some particularly twisted crimes. Together, they bicker and banter their way across Manhattan and the outer boroughs, solving cases with brains and screwball comedy banter. Delightful.

Christian Jules Le Blanc and Tracey E. Bregman, The Young and the Restless

Sexy, smart, and a little mischievous, Michael Baldwin and Lauren Fenmore Baldwin are one of the hottest super-couples of CBS Daytime.

He's played Baldwin since 1991; she's portrayed Fenmore since 1983.

Now, that's commitment.

Jonny Lee Miller and Lucy Liu, Elementary

Few pairings are as time-tested as Sherlock Holmes and Doctor Watson, the great detective and the loyal physician who keeps the gifted genius in line. In this clever and modern twist—now in its seventh and final season—Jonny Lee Miller is Holmes to Lucy Liu's Doctor Joan Watson. These brainiacs are equally prickly but devoted to one another: When Watson tells Sherlock, "We're partners," he responds, "No, we're much better than that. We're two people who love each other. We always have been."

Penn Jillette and Teller, Penn & Teller: Fool Us

After four decades performing magic, Penn Jillette and Teller really know how to cast a spell. Together, the dynamic duo headline their playfully titled reality show Penn & Teller: Fool Us, daring practicing illusionists to outsmart them with spectacular trickery. Teller might not verbalize his thoughts, but voluble Jillette seems to understand what his partner's thinking. By now, mind reading just goes with the territory.

​Haley Lu Richardson and Cole Sprouse, Five Feet Apart

Stella is a 17-year-old cystic fibrosis patient whose life of routine is upended when she meets charming fellow patient Will; the two become increasingly close even as the risk of cross-infection keeps them physically separated. The charismatic leads played by Haley Lu Richardson and Cole Sprouse, gave weight to the teen romance when it opened in theaters this spring, but for anyone who missed it, Stella and Will's sweet rapport plays just as well on the small screen. All the better to weep in the privacy of one's own living room.
