Peter Facinelli has captured the hearts of millions of teenage girls with his role as Dr. Carlisle Cullen in the "Twilight" series. No wonder the actor also casts a long shadow over the Twitter-verse, with over 1.2 million people following his updates on the micro-blogging site. His tweets are so popular that fans recently voted him Worldwide Mr. Twitter. 
So far, Facinelli says he's tried to use his new status for good -- as well as a dollop of career promotion -- asking his loyal fans to donate blood or give money to cancer research. One thing he hasn't been able to do with his new influence is convince Kristen Stewart, the films' star, to join Twitter. With time and tweets, maybe Bella will become a convert.
Congratulations on being Worldwide Mr. Twitter. How did it feel to earn that title from fans?
I don’t know what my responsibilities for that are exactly. I'm not sure if I have to do people's laundry or give tax incentives, but it's endearing. It's nice people would come together even on something as silly as Mr. Twitter. I'm just going to try to continue to entertain people and make them laugh.
How much time to spend on Twitter?
I tweet once or twice a day. When you're working, you always have down time on set. It beats visiting the craft service table. When I'm with my family, I tweet less, because I'm spending time with my kids. But on the set, I'll pull it out of my pocket and read responses. It's like checking email.
When did you start?
Maybe four or five months ago. A friend of mine knew a lot about multimedia networking and he set up an account for me, because I'm pretty computer illiterate. So I started sending out messages to fans, and it seemed like a great way to connect with them. I get to entertain, promote things I'm doing, and share charity events that I do. It's fun to get feedback and answer their questions, and it puts the media in your own pocket.
Did you expect you'd become so popular?
When I started out, I had 80,000 followers. I made a bet with a friend, who said he bet I couldn't get 500,000 followers in two weeks. I asked the fans what he should do if he lost the bet. They said that he should dance down Hollywood Boulevard in a binkini to the song "Single Ladies." So they actually did it, and I won. I turned around and had the clothing store Affliction sponsor the event, and the fans came out to watch, and we were able to raise $10,000 for the Christopher Reeve Foundation. This silly little bet made a difference because of Twitter.
You sometimes tweet about your family life. Do you worry you're sharing too much personal information?
My personal life is in the media anyway. I'd rather share information about what I'm up to or a picture than have someone jumping out of bush and taking a shot of me.
