Jennifer Garner has confirmed that she and husband Ben Affleck are expecting their second child, ending months of baby bump speculation.

Garner jokingly admitted the pregnancy in an interview with Access Hollywood at Walt Disney's 10th Anniversary party for the Baby Einstein line of merchandise Wednesdy, saying, "I just had a lot of carbs for breakfast." She added, "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."

Kidding aside, the former Alias star said she and her hubby are "so excited" for the new child, whose sex has not been revealed.

Garner and Affleck married in June 2005, and Garner have birth to the couple's first daughter, Violet, in December of that year. - Adam Bryant
