Kendra Wilkinson and Crystal Hefner are closer than people think despite having some rough patches in their friendship. The 35-year-old recently told Us Weekly, "We will always be friends." Crystal was married to the late Playboy founder and publisher, Hugh Hefner, for five years before he died in 2017 at 91 years old. Meanwhile, Wilkinson was known as a "girlfriend" of Hefner's and lived in the Playboy Mansion from 2004 to 2009.
