Janel Parrish and her “Dancing with the Stars” partner Val Chmerkovskiy are smoking the Season 19 competition with their sultry jazz performances and uber-sexy jive routines. In fact, their chemistry on the ballroom floor is so fiery that it’s rumored the two are having a secret romance. So, are the ABC reality stars just dancing partners, or are Parrish and Chmerkovskiy just another pair of “Pretty Little Liars”?

The buzz surrounding the possible “DWTS” romance came after Parrish split with actor Payson Lewis, whom she was dating when the 2014 competition began. Lewis, who appeared on episode 6 of “How I Met Your Mother” in 2010, confirmed the breakup in a thoughtful Instagram caption on Thursday.

“All good things must come to an end. Thank you for the happiest year and a half of my life. I will always love you @janelparrish and I wish you nothing but the best. Forever #teamjanel,” he posted, adding a photo of the two lounging in the sunlight.

Did Chmerkovskiy have something to do with Parrish’s split from Lewis? Although the timing of Parrish’s breakup is rather peculiar, it’s difficult to credit, considering Lewis’ kind farewell post to his ex.

"Access Hollywood" decided to get to the bottom of the relationship mystery by requesting the “DWTS” duo take a lie detector test. Hosts Billy Bush and Kit Hoover pried into Parrish and Chmerkovskiy's lives by asking some off-the-wall questions, like whether or not the two have given each other massages after vigorous dance practices (they both said yes) or had dreams about one another.

While Parrish claimed she's never had a dream about Chmerkovskiy -- except for a few involving dancing -- her partner quipped that Parrish has appeared in a few nightmares of his. But the jokester quickly redeemed himself when he admitted to having some sort of emotional meltdown when Parrish was partnered with Artem Chigvinstev in Week 5’s switch-up.

“Right now Ukrainians and Russians are not really getting along anyway. So adding the mixup into the mix and adding Janel into this burlesque number, yeah, I had some sort of emotions about that,” Chmerkovskiy said in response to Parrish’s spicy routine, which judge Julianne Hough referred to as a little raunchy.

Before the lie detector test concluded, the hosts asked both “DWTS” competitors if they had romantic feelings for one another. Parrish quickly dismissed the question while Chmerkovskiy toyed with the hearts of “DWTS” fans everywhere just to see if the lie detector test actually worked. After a few moments of “does he/doesn’t he,” the handler of the machine said, “I think there’s a problem with the equipment.”

Guess we’ll have to tune in to next week’s episode of “Dancing with the Stars” to see if we can tell whether the duo’s chemistry is just for the cameras or the real deal.
