Ian Ziering's daughters have never seen Beverly Hills, 90210.
The 61-year-old actor played the role of Steve Sanders in the teen drama's entire 10-season run from 1990 to 2000 but has "zero cool points" with his children Mia Loren, 14, and Penna Mae, 12, - whom he has with his ex-wife Erin Ludwig - as they are a bit "too young" to watch the series at the moment.
