Kendra Wilkinson seems unsure of her husband's loyalty judging from the "Marriage Boot Camp" star's warning to Hank Baskett.

The controversial couple's stint in reality show "Marriage Boot Camp" helped them recover from a cheating scandal that Hank Baskett got embroiled in last year. However, Kendra Wilkinson claimed her husband might slip back to his old ways after they leave the series.

According to a report from Perez Hilton, the outspoken TV personality opened up about her worries and gave the NFL star a stern warning during the season finale of "Marriage Boot Camp."

"I warned him that if he ever f-ked up, I would either kill him or never speak to him again," the former Playboy Playmate said.

"I am nervous that Hank could go back and fall back into that place and if that happens, let's just call our relationship over."

While Kendra Wilkinson has been open to her husband about her doubts, Hollywood Life reported about how the mother-of-two previously insinuated that Hank Baskett might not be strong enough to be completely honest with her.

During a counselling session with "Marriage Boot Camp" mainstay Jim Carroll, the ex-girlfriend of Hugh Hefner scoffed at the former football player.

"I don't think you're strong enough to go through this shit, Hank," she told Hank Baskett. "I think you're gonna go the other way and commit suicide or something."

The doubts of Kendra Wilkinson were revealed on "Marriage Boot Camp" after she posted an Instagram tribute to defend Hank Baskett.

The image uploaded last July 17 was reported by Us Weekly, showing the parents of five-year-old Hank Jr. and one-year-old Alijah looking sweet while at a formal event.

"This is the love of my life...A true man," Kendra Wilkinson captioned the photo.

"I believe in forgiveness and I believe in him. I take my vows very serious and won't let people's beliefs get in my way of what I know."

"Everyone that truly knows [Hank Baskett] knows the truth and everyone who doesn't creates their own ideas [and] that's ok[,]" she said.
