It's another girl for Ian Ziering!

Ian Ziering, 49, and his wife, Erin, have welcomed their second child — another girl!

And get this: Their first child, Mia Loren, was born exactly two years earlier — to the day! Can you imagine having two kids with the exact same birthday? What are the chances of that? I'm not sure this is the best news for their first daughter, Mia Loren, but she did get herself a beautiful baby sister for her birthday!

OK, so details!

According to People Magazine, baby arrived last Thursday, April 25, 9:21 a.m., in Los Angeles, California, weighing in at 6 pounds, 9 ounces. And the name is...Penna Mae Ziering.

“We didn’t plan it!” Ian tells People of the birth-date coincidence. “Mia was born a week late and Penna was a week early.”

As for the name, Penna is named after Ian's late father, Paul, and her middle name, Mae, is from Erin's side: Erin's mother, grandmother and great-grandmother all share the same middle name.

Congrats to the family!
