Former Beverly Hills, 90210 star Ian Ziering is a dad again after his wife Erin Ludwig gave birth to a baby girl on Thursday (25Apr13).

The new arrival, Penna Mae Ziering, was born on her elder sister Mia Loren‘s second birthday.

Ziering tells, "We didn’t plan it! Mia was born a week late and Penna was a week early."

The actor's newborn arrives as he prepares to become the latest celebrity to strip onstage in Las Vegas as part of the Chippendales revue at the Rio All-Suite Hotel and Casino. The 49 year old will join the show for four weeks from 6 June (13).
