Kendra Wilkinson cheated during her plural relationship with ex-boyfriend Hugh Hefner, 82, because she “had to have sex.”

“I had to have sex every now and then, so I had to kind of sneak it,” Kendra told Us Weekly this week.

The 23-year-old Girls Next Door star will marry the NFL’s Hank Baskett in a ceremony on The Playboy Mansion in June.
