It’s a girl for Ian Ziering!
The actor’s wife Erin delivered daughter Mia Loren Ziering at 10:09 p.m. Monday in Los Angeles, PEOPLE confirms. Weighing in at 7 lbs., 6 oz., the baby girl’s name begins with ‘M’ in honor of Ian’s late mother Micki, a source tells PEOPLE.
“Well, it’s official, I’m a dad!,” the former Beverly Hills, 90210 star, 47, wrote on his Facebook page.
“As I sit holding Mia, Erin sleeps the most beautiful sleep. My thoughts race with visions of a brighter future, only made possible by what happens today… or, last night! God bless us all.”
