Alyssa Milano is 'Romantically Challenged' -- But Only on TV

Alyssa Milano made a return to comedy after years on "Charmed" with her new ABC series "Romantically Challenged," airing tonight on ABC.

"When I first read the 'Romantically Challenged' script, I thought to myself, 'I did this for eight years during my youth, no problem,'" Alyssa tells ET. "Then creeping closer and closer to the date we were going to start shooting, I got really nervous. I think a lot of that plays into the mental aspect that you are actually going to be shooting in front of a live audience."

But the night of the first taping, Alyssa experienced déjà vu and calmed down.
