The former costars first met on the set of the 2005 independent film "Perception," and on their first day of filming, the pair were immediately thrown into a steamy situation.

"The first day all we did was we made out in a car for the whole day," Meyers, 40, recalled.

"That happens a lot on movies," the USA star, 37, mused. "It seems like the sex scenes and the makeout scenes, they do that first. It's like. 'Hi, nice to meet you!'"

Meyers, who married wife Alexi Ashe in Martha's Vineyard in September 2013, admitted that the passionate scene left him with a deeper connection to Perabo, who is currently engaged to longtime boyfriend Stephen Kay.

"We made out so much, at the end of the day I felt like we'd been together for five years," Meyers admitted.

"Yeah, I was like, 'I'm sort of bored with you,'" Perabo quipped.

"Yeah, I am too, bye! Let's go see other people," the host joked.
