Kristen Stewart and Robert Pattinson: Now on Twitter

Robert Pattinson and Kristen Stewart, two fiercely private celebrities, are now putting their fingers on keyboards to post 140-character tweets on Twitter.

Still wanting to keep everyone outta their business, they haven't created their own personal Twitter accounts but they have posted a few tweets to thank fans on Twitter.

Robert tweeted: "Thank you for making NEW MOON #1. It's very exciting to be a part of something embraced by so many people. I hope you are looking forward to ECLIPSE as much as I am."

Kristen tweeted: "You all have proven you're the most amazing fans in the world once again."

Robsten's tweets can be found on the Twilight Twitter page.
