Jessica Simpson celebrated her unborn son at a Tom Sayer-themed baby shower over the weekend. "I'm so excited to have a son," the singer turned fashion designer told People magazine, "He got all these cute vintage cars and I got a lot of little leather jackets I can't wait to try out!"

Simpson wore a curve-hugging bright blue dress at garden-fete bash, which was hosted by Ashlee and mother Tina. Simpson revealed that she was having a baby boy on Jimmy Kimmel Live! last month, mentioning that she and Eric Johnson were thinking of naming the little fella Ace. "I didn't grow up with a brother, and I think the unknown is really exciting," Simpson said of her daughter's upcoming big sister" status. "I can't wait to have that connection with our little man."

Bango music helped set the vibe for the party, with 48 guests served Champagne with fresh blueberries in vintage baby bottles with custom made straws. Wow. Goodie bags given to the lucky guests included blue nail polish, lip gloss and, wait for it, condoms. Children were treated to grilled cheese while the adults got chicken. "I always love some fried chicken," the 32-year-old said.

Simpson famously gained some 60 pounds during her first pregnancy with daughter Maxwell Drew, now 11 months old. This time, she's been working out with trainer to the stars, Harley Pasternak.
