Kendra Wilkinson is rumored to be upset over not receiving a ''save the date'' card for former beau Hugh Hefner's June 18 wedding to Crystal Harris.
According to popeater.com, sources close to Crystal say the 24-year-old is unsure whether she wants her future husband's former playmates to attend her nuptials.
"This is Crystal's special day, and she doesn't want all of Hef's exes there," a friend tells popeater.com. "What woman would?"
Meanwhile, Kendra told E! Online that she blames Crystal, not Hugh, for the situation.
"It's Crystal that does the wedding planning. She's the girl," Kendra tells E! Online. "If she doesn't give me a save-the-date soon, I'm going to have to put in my save-the-date with the other wedding."
