Ian Ziering Welcomes Baby No. 2!

Ian Ziering and his wife gave birth to a baby girl on Thursday, Celebuzz can report exclusively.

And in another sweet surprise, the newest addition to the family was born on the same day as his 2-year-old daughter Mia Loren, who was brought into this world on April 25, 2011.

“It wasn’t planned,” a source tells CB! “It was just great timing.”

Erin was actually due May 1.

The Beverly Hills, 90210 star’s wife of three years went into the hospital for the delivery a couple days ago, and the family is expected to leave with their new bundle of joy Friday.

Celebuzz was the first to report that Ian, 48, and Erin, who got married in May 2010, were expecting a baby girl.

“I feel blessed, having a family is something that I’ve always wanted,” the happy father told the PEOPLE in October 2012. “Having a second child is the realization of a dream come true.”

A call to Ziering’s rep was not returned by press time.
