Kelly Clarkson cancels big wedding plans: Most bizarre celebrity wedding?

The wedding is off! Well, sort of. Kelly Clarkson was planning to have a big, lavish wedding with talent manager Brandon Blackstock at the end of October. But now, she's decided to elope instead.

The awkward part? The couple already sent out a "save the date" to all the wedding guests! So the "American Idol" alum broke the news to her guests as classily as possible, sending out an engagement photo of the two and adding the note "Thank you so much for understanding, but it's just going to be me and Brandon and his two kids and the minister."

Canceling plans after sending out invites to hundreds of people is definitely a little embarrassing, but it's nothing compared to some of the other stuff celebrities have done at their weddings.

Britney Spears shocked guests with a "surprise wedding ceremony" to Kevin Federline out of the blue. Kendra Wilkinson held her wedding to Hank Baskett at her ex-boyfriend's mansion (the Playboy mansion, that is.) And Pamela Anderson wore a white string bikini to her wedding with Kid Rock.

As you can see, there's tons of bizarre celeb ceremonies to choose from. Which star has had the strangest wedding?
