Denise Richards says she was not dating rocker Richie Sambora while he was married to her former pal Heather Locklear.

"I did not interfere with their marriage," she said.

Richards, 37, told Ryan Seacrest that she remained friends with Sambora after her friendship with his then-wife Locklear was over.

They started dating after simultaneously going through "awful" divorces and caring for ill parents.

Richards said she "followed her heart," but added that nothing happened while Sambora was married. She and Sambora are no longer dating but remain friends.

Richards also told Seacrest that her ex-husband Charlie Sheen "cut me off of child support last week."

She also said she doesn't understand why Sheen called for a boycott over having their young daughters on her reality show, given that they've always been in the public eye.

Richards called Seacrest's KIIS-FM radio show to promote her upcoming reality show "Denise Richards: It's Complicated." Seacrest is producing the show.
