Jennifer Garner Debuts Post-Baby Body In Las Vegas (PHOTO)

Jennifer Garner may have given birth to her third child in February, but you would have never known it by looking at her on the red carpet Tuesday. The actress made her official return to the spotlight when she debuted her post-baby body at CinemaCon in Las Vegas.

Garner and her husband, Ben Affleck, added a baby boy to their brood less than two months ago.

"We are happy to announce on February 27, Jennifer gave birth to a healthy baby boy, Samuel Garner Affleck," Affleck wrote on his Facebook page a few days after the birth.

Though we haven't gotten a glimpse of baby Samuel just yet, we've seen Garner out and about with her youngest daughter, Serpahina, 3. The couple also have another daughter, Violet, 6.
