Alyssa Milano On Set Of Castle

The wait is over for the Castle episode featuring Alyssa Milano and ABC was kind enough to show us a few behind the scenes moments. The funniest parts being a cute clip of Alyssa describing Nathan Fillion as a Diva as well as the moment when Nathan says he was trying to class up the show, to which Alyssa replies with a smirk, “Cause I’m classy!”

Don’t forget to watch Monday night at 10pm EST!
