Ian Ziering is going to be a dad again!

The former Beverly Hills, 90210 star and his wife Erin are expecting a baby girl.

“They are so excited,” a source told CELEBUZZ. “They’re telling all their friends they’re having another girl. Erin’s gushing about it, and they’ve already started decorating the nursery.”

The couple who married in May 2010 are already parents to 18-month-old daughter Mia Loren.

After the birth of Mia, the proud dad said experiencing her birth was most incredible thing.

“I was in awe when Mia began to emerge. No matter what you have seen before — whether in biology class or National Geographic – nothing can prepare you for looking at your own child for the first time. The doctor put Mia right onto Erin’s chest, where her first cry was quickly soothed by her mother’s embrace. I’ve seen some incredible things in my life, but nothing compared to seeing this,” he told People.
