A report that surfaced in British magazine Grazia (via The Independent) claims the 51-year-old Hollywood hunk was on "cloud nine" after going on a date recently with the 33-year-old Orange is the New Black star in L.A.
The story quoted a source saying Cruise—who became friends with Prepon through Scientology as she's also a devout follower—took the actress out for a posh dinner at The Renaissance at The Manor Hotel. Not only that, but the former Days of Thunder star purportedly picked up the actress in a classic car and surprised her with a vintage 1979 bottle of merlot.
The insider alleged that the evening went so well, the duo returned to the restaurant for a second date over Sunday brunch, and then she accompanied him to a party at fellow Scientologist John Travolta's home a few days later.
However don't get your couch-jumping hopes up just yet.
When contacted by E! News, Cruise's rep smacked down rumors of a romance, saying the report is "false."
Since then, he's concentrated on work, starring in last December's thriller, Jack Reacher, and the summer sci-fi blockbuster Oblivion.
As for Prepon, who shot to fame playing Donna Pinciotti in Fox's hit sitcom That '70s Show, she's previously been linked to actor Chris Masterson.
