Ashlee Simpson Debuts Post-Pregnancy Figure

Three weeks after giving birth to first child Bronx Mowgli Wentz, Ashlee Simpson has made her first public appearance. The new mom was spotted showing off her post-pregnancy figure as she stepped out to watch hubby Pete Wentz performing with his band Fall Out Boy.

Wearing a black dress, Ashlee hasn't gotten back into shape yet. But the 24-year-old beauty looked happy while attending the concert at the Troubadour in West Hollywood on Monday, December 8.

"My weight and my pant size are the absolute last thing I am concerned about. I am only concerned with having a healthy pregnancy and a healthy baby," the younger sister of Jessica Simpson told Us Weekly. "People who judge pregnant women's weight need to get a life."

Ashlee Simpson and husband Pete Wentz welcomed their first son on November 20. Their baby boy was named after the Disney character Mowgli, a 10-year-old boy brought up by wolves in the Jungle Book.
