Bridesmaid Holly Madison told People Magazine that Wilkinson and Hank Baskett were married Saturday at sunset before an altar decorated with white flowers in a ceremony attended by 300 guests, including Playboy Magazine founder Hugh Hefner.
Wilkinson, whose life as one of Hefner's girlfriends was chronicled in the reality television series "The Girls Next Door" on E! Television, wore a white dress with a "tight bodice and poofy skirt," said Madison, a "Girls Next Door" co-star.
"She looked like a princess," Madison told People. "It was a beautiful setting for a wedding. It was a princess dress, which was fitting. It was really pretty and she looked gorgeous."
Wilkinson and Baskett reportedly danced the first dance to George Strait's "I Cross My Heart," while the bride's second dance was saved for Hefner.
