The Secret Life Of Timothy Green Jennifer Garner heels baby weight dress david letterman

Baby weight? What baby weight?

Jennifer Garner posed for photos outside of The Late Show With David Letterman on Tuesday evening in NYC, and we think this is the best Ben Affleck's wifey has looked in years. After giving birth to son Samuel 7 months ago, we can't believe how much she's slimmed down!

Jen is currently promoting The Odd Life Of Timothy Green, and over the weekend we spotted Ben spending some quality time with the kids in Pacific Palisades. Jen may be missing the couple's three children, but it sounds like she's mellowed out a bit since the birth of her first kid 6 years ago and she even compares herself to the mom she portrays in the film.

“[My parenting style] evolves all the time," Garner told FOX411 at a recent interview. "With my first child I was a little more like Cindy Green in this movie, who is just obsessively trying to make sure her child is happy at every moment and always trying to control his environment and make sure he has everything he might possibly need. I was just a little bit neurotic as many first-time moms can be."

We snapped a shot of Jen later in the day, and she looks just as stunning here:
