Jessica Simpson is looking hot! The starlet and mother of two flaunted her newly svelte bod in a photo from a Weight Watchers commercial shoot, and she looks better than ever.

Simpson tweeted the photo yesterday:

The buxom blonde sports a simple white blouse, dark jeans and a glowing smile on set. She's in a field and the lighting is almost as stunning as she is! Simpson is making a triumphant body comeback following the weight struggles she suffered after her back-to-back pregnancies with daughter Maxwell Drew and son Ace Knute.

Radar Online reports that the weight loss is likely a crucial step in Simpson finally walking down the aisle for the second time. After her divorce from Nick Lachey and heavily publicized romances with John Mayer and Tony Romo, Simpson found love -- and babies -- with former NFL player Eric Johnson. The couple have been engaged since her pregnancy with Maxwell, but the ever-stylish 'Style Star' hostess wants to be able to fit into a gorgeous gown for the occasion, so their actual wedding has been on hold!

Sources told Radar that Simpson and Johnson are considering intimate destination weddings for their nuptials, with options including Italy and Hawaii. In the case of the latter, J-Simp is going to look mighty fine in her bikini on the beach!
