Ashlee Simpson-Wentz and husband Pete are reportedly selling LA mansion

Ashlee Simpson-Wentz and husband Pete are reportedly putting their LA mansion up for sale.

The 30-year-old Fall Out Boy rocker and wife Ashlee, 25, who have an 11-month-old son Bronx, are putting the Beverly Hills house up for sale to make room for their baby boy.

A source said: "The house is built into the side of a giant hill and it doesn't really have any yard. Now that Bronx is getting older, they realised that really isn't a child-friendly house.

"They are going to sell this house and look for something that will be better suited to young children."

Ashlee bought the Mediterranean-style home in January 2007 for $4.5million.
