It can be a challenge to lose weight after having two children in a short period of time, but Jessica Simpson is grateful for the support she received through Weight Watchers.

In a new ad for the brand, the former reality star shows off her progress in a figure-hugging Alexander McQueen white dress.

Echoing what a lot of women probably felt, she begins, "I wasn't sure what to expect at the meetings, but I really love going. It reminds me we don't have to do this alone. It's so much better to have some backup, and to do it together, because we all face similar challenges."

Excited about how far she's come, the 33-year-old adds, "I have a newfound determination that I'm really proud of. I can honestly say I've never been happier." Check it out in the player below.
