Former Beverly Hills, 90210 star Ian Ziering is set to be a dad again.

The actor's wife Erin is pregnant with the couple's second child and she is due to give birth next May (13).

The 48 year old tells People.com, "I feel blessed; having a family is something that I've always wanted. Having a second child is the realisation of a dream come true."

The couple is already parents to one-year-old daughter Mia Lauren, and Ziering reveals his little girl is excited to be a big sister.

He adds, "We tell her 'baby' and point to Erin's belly. Now she points to Erin's belly and says, 'Baby.'"

The pair wed in 2010.
