Playboy Hugh Hefner's ex-girlfriend, Kendra Wilkinson, said she feels sorry for hurting him before the break up.

In a recent interview with Us Magazine, the former Girls Next Door star admits to cheating on Hef.

I'm very sorry to have hurt Hef, she said. Playboy made me who I am, and Hef has done more for me than anyone else. In my heart, I will always love Hef and Playboy.

Wilkinson was so sorry that she stopped by the mansion to apologize in person. Hef was hurt, but he understands, she told E!. He knows me...

Wilkinson did not confirm the date of her wedding.

I'm still trying to think about all that stuff, she says. I am waiting for Hank [Baskett, of the Philadelphia Eagles]. After the Super Bowl, he'll come out and live with me, and we'll start planning the wedding and start thinking about all of those things like who is going to walk me down and where it's gonna be.
