Kendra Wilkinson may have to hit bottom before she's back on top again. A new preview for the third season of her WEtv show, Kendra on Top, shows the former Girls Next Door star, 29, struggling to keep it together in the wake of husband Hank Baskett's cheating scandal earlier this year.

In the clip, Wilkinson is seen breaking down in a friend's arms over rumors that Baskett, 32, hooked up with a transgender model while she was eight months pregnant with their second child, daughter Alijah, 5 months. (They also have a 4-year-old son, Hank IV.)

"I didn't do anything," her former NFL pro husband insists, as headlines flash across the screen. A second later, Wilkinson says, "No one believes you." Later in the teaser, she asks, "Did you think about your family when you did what you did?"

A previous clip from the upcoming season showed the ex-Playmate talking about flushing her wedding rings down the toilet after learning of Baskett's infidelity. "Our marriage is down the drain!" she said.

Watch the preview above. Season three of Kendra on Top premieres on Friday, Oct. 3, at 10 p.m. ET/PT.
