Bridesmaid dresses may have a bad wrap, but the fugly fashion rule clearly doesn’t apply when it comes to Jessica Simpson. Looking stunning in a midnight blue, floor-length gown, the new mom — who gave birth to son Ace just three short months ago — practically glowed at an October 11 wedding.

The 33-year-old Jessica and fiancé Eric Johnson attended the ceremony of publicist Lauren Auslander in Newport, Rhode Island. It’s the second time Jessica’s played bridesmaid recently; she was maid of honor for her best friend, CaCee Cobb, back in December.

As for when Jessica and Eric will make their own trip down the aisle, it’s anybody’s guess. Finding time to plan a wedding has to be hard seeing as the two have been so busy with their babies — 17-month-old daughter Maxwell and their most recent addition, born on June 30. How did Jessica ever find time to get her body back into shape so quickly?

Despite their hectic schedules, getting hitched sounds to still be the plan for Jessica and Eric. The day after attending Lauren’s ceremony, Jessica shared a photo of herself and Eric’s mom.

“Beautiful morning with my future mother-in-law and MoJo to my babies,” she captioned the pic. Looks like Jess is already a full-fledged member of the Johnson family!
