New Dad Ian Zierling Shows Off His Biceps

Not bad for a 47-year-old!

Ian Zierling, from the original Beverly Hills: 90210, showed off his daddy guns while shopping for some groceries for his family.

He and wife Erin Ludwig welcomed their first child, a baby girl named Mia Loren Ziering, into the world on Monday night!

We hope the actor enjoys his newest and most important role to date as a father.

Congrats, guys!
