Kelly Rutherford Welcomes a Girl!

Kelly Rutherford is a proud new mama to baby girl, a week after telling OK! she was ready to pop!

"I could go into labor at any moment!" the proud mom joked to reporters at the Third Annual Kidstock Music and Arts Festival in Beverly Hills on May 31.

"No, she’s not due until next weekend," Kelly reassured everyone, adding that her son is excited to meet his sister.

And now 2-year-old Hermés, Kelly's son with ex Daniel  Giersch, has a new sister, Helena Grace Rutherford Giersch. She was born Monday in L.A., weighing in at 8 pounds, 12 ounces, her rep says, adding, "Kelly and the baby are doing just fine."
