The mother-of-two showed off her hot post-baby bod in an orange mini-dress at her friend Kathryn Sykora's baby shower at The Churchill restaurant in Los Angeles Sunday.
Posting several photos from inside the party, the blonde beauty called actress Odette Annable a "Force to be loved," in one shot of herself cozying up beside the "You Again" star.
Later, singer Stephenie Pearson joined the duo, and Jessica shared a picture of the three girls enjoying a three-way kiss with the cheeky caption, "Girls night out…with our guys watching."
Simpson certainly earned a night out with her girls -- she recently revealed that she's reached her goal weight.
"When I started Weight Watchers, I didn't know what to expect at the meetings," the 33-year-old fashion mogul said in a recent commercial for the company. "It reminds me we don't have to do this alone. It's so much better to have some back up since we all face similar challenges. I can honestly say I've never been happier!"
We love to see that she's happy and healthy!
