Is Tom Cruise dating Laura Prepon?

Could it be? Could Donna whom we all know and love from That '70s Show actually be transforming into Wifeybot 4000?

Rumor has it Laura Prepon and Tom Cruise have been an item for something like five months. The Orange is the New Black actress is a gorgeous Scientologist, so they do have that in common. But really?

The New York Post's Page Six says it's so. A source tells the paper the couple have been seeing each other since last fall but are trying to keep it as quiet as possible.

"It's the buzz on the set of her show," the squealer said.

British mag Grazia reported in November that Cruise, 51, picked up Prepon, 34, in a vintage car and had a bottle of 1979 Merlot waiting when they arrived at the Manor Hotel.

"They spent three hours laughing and joking. It's clear Tom is smitten and after the date he was on cloud nine," according to Grazia's account. "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."

Reps for Cruise and Prepon have denied the relationship.

"They see each other at some functions, but they are not dating," an insider told Us Weekly in the fall.
