Nearly one week after Ashlee Simpson wed fiance Pete Wentz in a private L.A. ceremony, OK! has learned that the bride's family--sister Jessica Simpson and parents Joe and Tina Simpson--has returned from a five-day long vacation in Cabo San Lucas, Mexico.

An eyewitness tells OK! that Jesscia and her parents touched down Thursday night in a private plane at Burbank's Bob Hope Airport. The trio scooted off to the Mexican Resort town last Sunday following Ashlee's wedding at the Simpson family home in Encino, Calif.

But the big question still remains: Where are the newlyweds? Rumors are swirling that the couple may have jetted to Cabo as well, and some sources say both Ashlee and Pete actually arrived home tonight with the Simpson family, somehow managing to hide from paparazzi.

Wherever they are, one thing is clear: The couple has succeeded in keeping the details of their honeymoon secret. On Tuesday morning, Pete jokingly told Ryan Seacrest on his radio show that he and Ashlee were actually honeymooning in the basement of their home!

If that's true, it seems Ashlee and Pete may be having the last laugh after all!

Stay tuned!
