Unlike fellow Hugh Hefner ex-girlfriend Holly Madison, Kendra Wilkinson never saw marrying the Playboy founder as part of her future.

Now that he's engaged to Crystal Harris, "he's where he wants to be in life, and you know, I'm happy for him," Wilkinson said on 'The Tonight Show.'

Her only concern was that she hadn't been invited to the wedding. So she alerted the media universe, and received an email from Hef shortly thereafter.

It read, "We haven't sent any 'Save the Dates' but if you can't make the planned wedding on June 18, we'll just change the date. Do you think I'd consider getting married without you being there?!"
