Ashlee Simpson-Wentz and Pete Wentz threw their son a "rad" first birthday party on Saturday (21.11.09).

Bronx Mowgli - who actually turned one on Friday (20.11.09) - was treated to a 'SpongeBob SquarePants'-themed bash at his grandparents Joe and Tina Simpson's house in Encino, California, which even included an impersonator dressed as the goofy, yellow sea sponge.

Ashlee Simpson-Wentz is to star in the Broadway production of 'Chicago'.

The 25-year-old star played murderess Roxie Hart in the London West End version of the musical and is now reprising the part in New York's famous theatre district.

Ashlee Simpson says husband Pete Wentz loves her stretch marks.

The singer-and-actress admits her body has changed since giving birth to the couple's 11-month-old son Bronx but knows the Fall Out Boy rocker still finds her attractive.

Ashlee Simpson and Pete Wentz are selling their house.

The singer-and-actress and her Fall Out Boy star husband have put their $4.5 million home in Beverley Hills, California, on the market after deciding it wasn't "kid friendly" enough for their son Bronx.
