ashlee simpson-wentzAshlee Simpson-Wentz celebrated her 24th birthday with a white-trash themed party at the weekend.

The party for family and friends took place at her parents home in Encino, California on Friday night and one party guest told People magazine that the singer didn’t let her pregnancy get in the way of dressing up: “Ashlee loves themed parties and costumes.

“Ashlee wore Daisy Dukes and platform flip-flops with a bathing suit and a fake tattoo around her belly.

“[Her sister Jessica Simpson] was wearing a crazy leopard-print dress that showed off a lot of cleavage [and their dad] Joe wore a cut-off muscle T-shirt and a mullet wig. It was funny.”

The theme also extended to the food served at the event: corn dogs, macaroni & cheese, chicken fingers and French fries.

Ashlee is due to give birth to her first child next month. She married dad-to-be Pete Wentz in May this year.
