It's another girl for Ian Ziering!
The former "90210" star and his wife, Erin, welcomed their second daughter on Thursday, according to People.
The baby girl, named Penna Mae Ziering, arrived at 9:21 AM and weighed in at 6 lbs., 9 oz., according to the mag.
Penna now shares the same birthday (April 25) as her big sister, 2-year-old Mia - which Ian said was a surprise.
"We didn't plan it!" he told the mag. "Mia was born a week late and Penna was a week early."
The 49-year-old actor said Mia was thrilled over Penna's arrival.
"She couldn't wait to meet her," he said. "When she saw Penna she said, 'Baby sister!'"
Ian and Erin began dating in 2009 and announced their engagement in February 2010.
They tied the knot on May 28, 2010 in Newport Beach, Calif.
