Jennifer Garner sunglasses baby weight green dress set film

She's taken lengthy time-out from acting to have baby No. 3, and be a stay-at-home mom, but now Jennifer Garner is finally getting back to her second favorite role: movie star!

Mrs. Ben Affleck looked gorgeous in a green mini dress and nude sandals as she exited her luxury trailer and made her way to a film set in LA, on Wednesday afternoon. The 13 Going on 30 star's latest flick, Disney's The Odd Life of Timothy Green, hits theaters next month, and centers on a childless couple who buries a "child wish list" in their backyard, only to have a baby appear in their garden the next day.

Meanwhile Ben has been busy shooting the upcoming gambling drama, Runner Runner, in Puerto Rico with Justin Timberlake and Gemma Arterton.
