Jennifer Garner finally confirmed Wednesday what her baby bump has made clear for weeks – that she and husband Ben Affleck are expecting their second child.

"We're so excited, obviously," Garner told Access Hollywood at Walt Disney's 10th Anniversary party for the Baby Einstein line of merchandise.

Garner joked about the endless speculation – even crediting her obvious pregnancy to "carbs for breakfast."

"It always makes me laugh when people say 'Is she?' 'Isn't she?' It's like eventually you will know, so just chill out for a minute," she told Access Hollywood.

And thanks to her toddler Violet at home, Garner isn't sweating having another baby in the house.

"Yeah, been through it," Garner said. "It's all good, it's great. I'm really excited."
