Kendra Wilkinson has "never been sadder" in the wake of Hank Baskett's alleged affair.

The reality TV star, who has son Hank IV, four, and daughter Alijah, eight weeks, with her husband of five years, is still devastated by recent rumours he cheated on her with a transsexual model while she was eight months pregnant with their second child.

A source told UsMagazine.com: "She's strong, but she can't handle everything. [She's] never been sadder."

But Kendra's best pal Jessica Hall insists she is focusing on moving forward.

She said: "I'm extremely proud of her. Her show couldn't be more perfectly titled--she's always going to be on top. That's why it's called 'Kendra on Top.' She's going to come out on top always."

She added: "I absolutely love and adore that girl. She's been my best bud for five years."

Another insider said the former Playboy model, 29, is a "tough girl" and is "doing okay."

It was recently revealed Kendra's marital woes will be chronicled on the next series of 'Kendra on Top'.

A spokesperson for WE TV confirmed: "We are currently in production on season 3 of 'Kendra on Top'. And yes, we are covering her reality."
