Years before Ryan Guzman was starring alongside Piper Perabo in the crime drama Notorious, she had already won his heart.

The 29-year-old actor sat down with ET's Katie Krause recently, where he admitted that he had a bit of a crush on his co-star when he was a teenager.

"Coyote Ugly was the one," Guzman said, recalling Perabo's 2000 musical comedy that cemented his affection for the star. "I remember watching that… I think everybody had a crush on her."

"I have a crush on you, Pipes!" the actor confessed.

In Notorious, Guzman plays a production assistant to a news producer (played by Perabo) who is a master at manipulating the media cycle. In real life, Guzman himself has had to spin and shut down a few tabloid stories of his own -- including a rumored romance with his The Boy Next Door co-star Jennifer Lopez.

"[There were] just assumptions that we were dating, you know, talking, blah, blah, blah," Guzman recounted. "She's just a friend of mine and I truly value her friendship."

That doesn't mean that the two didn't have some pretty hot and heavy scenes to shoot together while filming the 2015 erotic thriller. However, J.Lo doesn't top his list when it comes to best co-star kisser.

"Well [Lopez] marked me as her No. 2 'best kisser,' so she's getting No. 2," Guzman joked.

As for the co-star that tops his list? The young actor actually let a little spoiler slip, naming his Notorious co-star, Aimee Teegarden.

"Aimee's up there, I think," Guzman said, contemplating the list of women he's kissed on screen.

When asked to confirm that his character actually kisses Teegarden's character as some point in the show’s future, Guzman admitted, "There's a kiss in there, for sure."

Notorious airs Thursdays at 9 p.m. ET/PT on ABC.
