blonde singer sunglasses baby weight

Jessica Simpson and Eric Johnson returned home to LA after a quick trip to the east coast for a friend's wedding in Rhode Island.

The 33-year-old singer looked svelte in black after much criticism about not losing the baby weight after giving birth to son Ace Knute in June ... but we'd argue otherwise!

The pair attended the wedding of Simpson's publicist Lauren Auslander in a beautiful seaside ceremony and left baby Ace and daughter Maxwell at home for the weekend. Sounds like a fun adults-only getaway!
