Ashlee Simpson and Pete WentzAshlee Simpson and Pete Wentz are reportedly planning to marry on Saturday after just over a month of engagement.

According to Us Weekly, the couple are finalising plans to marry at a “top secret” location this weekend and have not even told guests where the event will take place.

A source told the magazine: “Proper invites have not been sent out but instead guests have been given a ’save the date’ notice.”

The couple will hold an intimate rehearsal dinner on Friday night for “family and close friends only” and on Saturday, “all guests will be transported in shuttles to the wedding location.”

The couple announced their engagement last month promoting a flood of rumours that Ashlee was already pregnant with Pete’s child. The Fall Out Boy star denied the rumours immediately but his bride-to-be fed the stories with a series of ambiguous comments, culminating with the suggestion that “time will tell” whether or not she’s expecting.
