Former Days star Crystal Chappell who played Dr. Carly Manning 1990-93 joined Twitter a few days ago. Carly was Bo's romantic interest after Hope 'died' during the Cruise of Deception storyline.
This is really her according to her official web site. She was twittering from the Guiding Light set yesterday.
