Ashlee Olson Parker-Gellar or whatever is marrying Pete Wentz, that nice young girl who’s in some band? Or something:

Ashlee Simpson and Pete Wentz will wed Saturday, May 17 at a “top secret” location, a source close to the couple told Usmagazine.com.

“Proper invites have not been sent out but instead guests have been given a save the date notice,” the source told Us.

The rehearsal dinner – described by the source as “an intimate affair” for “family and close friends only” – will take place on Friday.

On Saturday, “all guests will be transported in shuttles to the wedding location,” the source explained.

Transported in shuttles? Space wedding! That sounds out of this world. And a good way of avoiding having to invite all those “primos” you’re not actually even related to.
