Happy Halloween! Jessica Simpson Shows Off Fabulous Post-Baby Body in Sexy Costume

New mom looks simply stunning while posing with her fiancé and the couple's 5-month-old daughter for a holiday family photo

Jessica Simpson is one hot Halloween mama!

The Fashion Star mentor posted this family photo of her posing with Eric Johnson and the couple's daughter Maxwell just in time for the holiday.

And while, yes, her fiancé looks pretty cool in a Braveheart-inspired outfit, and the little one is downright adorable dressed as a rooster, it's Simpson that we can't stop staring at.

The 32-year-old new mom, who has reportedly lost 60 pounds since giving birth to her baby five months ago, shows off her fabulous figure in quite the form-fitting costume.

"Happy Halloween!" Simpson wrote as the photo caption.

Indeed.
