Tom Cruise has secretly been dating "Orange Is the New Black" star Laura Prepon for several months, according to a new report from the New York Post's Page Six.

Shortly after his marriage ended with Katie Holmes in 2012, the 51-year-old actor is rumored to have struck up a romance with fellow Scientologist Laura, Yahoo News reported.

Even through the romance is trying to be kept under wraps, Laura's castmates are apparently beginning to suspect things are getting serious.

"It's the buzz on the set of her show [Orange is the New Black]," a source told Page Six.

Rumors that Cruise was dating the "That '70s Show" alum first surfaced when they were spotted dining out together at The Manor Hotel in Los Angeles last November, US Weekly reported.

Although the two have known each other for years, it was reported that Tom "pulled out all the stops to create a romantic ambience for Laura, as he picked her up in a vintage car and a bottle of 1979 Merlot waited at the table when they arrived to dinner," Yahoo News reported.

"They spent three hours laughing and joking. It's clear Tom is smitten and after the date he was on cloud nine," a source told British magazine Grazia at the time.

"They had their second date at the restaurant, too, meeting for Sunday brunch, and then she accompanied him a few days later to a dinner party at John [Travolta]'s home."

A source told US Weekly, however, that there was nothing going on. "They see each other at some functions, but they are not dating," an insider told US in November. 

Cruise and Laura's representatives have firmly denied the reports, according to Page Six.

Tom has been divorced three times. Laura, who famously portrayed Donna in That '70s Show, has never married.
