Jennifer Garner stopped by The Tonight Show with Jay Leno last night and while officially said she would not reveal the sex of her baby (due in the spring), it seems like she may have slipped and revealed that another baby girl is on the way!

When Jennifer told Jay that her two daughters Violet, 6 and Seraphina, 4, were excited about getting a baby sibling, she would only say they'll be expecting either a brother or sister. When pressed by Jay, the Butter actress confirmed that she knew the sex of the baby but added: "I'm not supposed to share it with you, Jay."

But later in the interview while discussing a sex scene with her Butter co-star Hugh Jackman, she joked that after some heavy breathing and making simulated sex noises for the film's soundtrack, she could have said to Hugh: "Let's name this baby Jackman. This is Jackman Louise, honey." Hmmmm, so why did Jennifer add Louise, and not Larry or Len or Lance?

Jay also asked the actress whether her husband Ben Affleck was hoping for a boy this time around and she responded: "At first I really thought so." But she added she's not so sure anymore because Ben once told her: "Well, we have girls, we know how to do girls, my girls love me. I'm the big guy in the house."
