Tom Cruise wasn't the reason for his breakup with Katie Holmes, says Holmes' ex-fiance, Chris Klein.

"Her being with Tom has nothing to do with her and I discontinuing our relationship," Klein said in an interview to air Monday night on "Access Hollywood."

"People move forward, people move on, it's what we do," the 26-year-old-actor said. Klein and Holmes called off their engagement earlier this year after dating for five years.

Cruise, 43, and Holmes, 26, went public with their relationship in April. They became engaged in June, and she is now pregnant with their first child.

"For me, what we had was very, very special, and I hope that she's making decisions that are making her happy and that she doesn't have people in her life leading her astray from what she wants and what she believes," replied Klein when asked about Holmes becoming involved in Cruise's faith of Scientology.

Klein's new movie, "Just Friends," co-starring Ryan Reynolds and Amy Smart, opens in theaters later this month.
