LOS ANGELES, Calif. --

After months of speculation, Jennifer Garner has officially confirmed she is expecting a second child with her husband, Ben Affleck, in a new interview with Access Hollywood’s Tony Potts.

”Thank you,” Jennifer told Tony at the Baby Einstein’s 10th anniversary celebration on Wednesday, at the Walt Disney Concert Hall in Downtown Los Angeles. “We’re so excited, obviously.”

Jennifer was coy with the news at first, joking with Tony as he wished her well.

“Congratulations. Can I say that?” Tony asked.

“For what?” Jennifer smiled.

“For baby number two,” Tony responded.

“Oh I’m not pregnant,” she giggled. “I just had a lot of carbs for breakfast. It’s just — what do they call it? A breakfast pouch? Bunch?”

Jennifer’s confirmation comes after weeks of speculation as her tummy size swelled to the visible baby bump she is currently sporting.

The child, whose sex Jennifer did not reveal, will be her second with Affleck.

Jennifer, 36, married Ben, also 36, in June 2005. They have one daughter – Violet, who was born in December 2005.

Jennifer’s pregnancy coincides with that of Luciana Damon, the wife of Ben’s pal Matt Damon. In March it was revealed that Matt and Luciana were expecting their second baby together, another daughter. Matt is also stepfather to Luciana’s 9-year-old, Alexia.

In June, Jennifer and Ben celebrated their third wedding anniversary. That same month, Ben told Access Hollywood’s Billy Bush, for “The Billy Bush Show,” family life was going well. “Things are pretty great,” Ben said. “We’re very happy. Things couldn’t be better. We’re kind of taking it easy and just kind of enjoying a little downtime at home.”

Jennifer told Tony the speculation over her baby in recent weeks has made her giggle.

“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 said.

And the expectant actress said she is prepared thanks to her daughter, Violet.

“Yeah, been through it,” Jennifer said. “It’s all good, it’s great. I’m really excited.”
