Unforgettable star Dylan Walsh announced the birth of his daughter on Tuesday and purposely concealed the mother’s identity, but RadarOnline.com has exclusively learned it is Leslie Bourque.

Walsh, 47, welcomed Amelie Belle on September 25 and said, “My best moment of 2011 would definitely be the birth of my daughter six weeks ago.”

But what the former Nip/Tuck actor didn’t comment on was the mother of his daughter, Leslie, who has been photographed with the actor all year.
