Kelly Rutherford is a mom-of-two! The 40-year-old Gossip Girl star welcomed her second child, daughter Helena Grace Rutherford Giersch, on Monday evening in Los Angeles. Weighing in at 8 lbs., 12 oz, Helena arrived at 9:20 p.m and is “doing just fine,” says a rep.

She is the second child for Kelly’s estranged husband Daniel Giersch. A rep for Kelly says he was notified of the birth and invited to the hospital, while Daniel claims a verbal agreement with Kelly to text or call him when she went into labor and delivered was not honored, leaving him to discover the news of his daughter’s birth through internet reports.

Helena joins big brother Hermés Gustaf Daniel, 2 ½. Kelly was due to deliver this past Saturday, and she was spotted out and about as late as Wednesday, taking a walk in Beverly Hills.

The pregnancy was announced in December.
