Former Beverly Hills, 90210 star has a new member to add to his zip code: Baby girl Mia Loren Ziering. The actor’s wife, Erin, gave birth to Mia Monday night in Los Angeles, according to People. Ziering wrote on his Facebook page: “Well, it’s official, I’m a dad! … 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.” The couple chose a name beginning with the letter “M” to honor the actor’s late mother, Micki.
