Singer Ashlee Simpson, 23, will wed "Fall Out Boy" fiancé Pete Wentz, 28, at a "top secret" location this Saturday, a source tells Us Weekly. "Proper invites have not been sent out," says the source, "instead, guests have been given a save the date notice."
The couple, who announced their engagement in April, have kept as quiet on wedding details as they have on Ashlee's rumored pregnancy.
The wedding weekend will begin Friday, with an intimate rehearsal dinner for "family and close friends only," says the source, "all guests will be transported in shuttles to the wedding location," which has been reported as being on the California coast in Santa Barbara.
