Laura Prepon has dismissed reports that she's dating Tom Cruise - calling the speculation "unbelievable".

The stars, both scientologists, were reported to have been seeing each other, going on secret dinner dates, for the past five months.

But actress Laura, who stars in Orange Is The New Black, told women's website "It's just so funny that, when people don't know, they just make stuff up. Apparently I'm dating Tom Cruise right now.

"And apparently he doesn't want me doing the show because I portray a lesbian and I'm a Scientologist.

"This is false; where are they even getting this stuff? It's unbelievable to me."

Tom, who was previously married to Mimi Rogers and Nicole Kidman, last divorced in 2012 after five years of marriage to Katie Holmes

A rep for former Dawson's Creek star Katie recently denied that she was dating Jason Segel.
