They are reportedly working on their marriage and happily back together, but many are wondering if strife has hit Kendra Wilkinson and Hank Baskett's marriage once again.

Hank Baskett Admits To Cheating?

The reality star posted photos of the couple's son Hank IV's fifth birthday party on her Instagram page over the weekend and even tweeted about the festivities-but there has been no mention of her husband in any of the posts, sparking more speculation that the couple's relationship is on the rocks once again.

"We had 20 little ninjas running around my house today for my boos party. I'm wiped out. #timefortheafterparty," she tweeted.

However, Baskett's absence from the photos and lack of mention in them have had many speculating however, as the couple is still working on repairing their marriage following a very public cheating scandal where Baskett reportedly cheated on his wife while she was eight months pregnant with their daughter Alijah, with a transsexual model named Ava Sabrina London.

The couple has since chosen to stay in their marriage, with Wilkinson even saying she received advice on what happened from ex-boyfriend Hugh Hefner-and that was what gave her the epiphany that she needed to remain in her relationship.

"When he said, 'Oh you know, we're humans, we all make mistakes, we all f-k up'-Hef saying that to me? It was like an epiphany just hit me," she said on the latest episode of her show, Kendra on Top.
