Livingston's alter ego was killed off in November 2007 by the so-called Text Message Killer, but that wasn't the last time that fans saw Emily. The character last appeared as a ghost in April 2013 as part of General Hospital's 50th anniversary celebration.
In 2005, Livingston won a Daytime Emmy in the Outstanding Supporting Actress category.
In addition to her work on General Hospital, Livingston also appeared briefly in 2011 as Taylor Walker on Days of our Lives.
Livingston is also part of the all-star soap-in-a-soap series Tainted Dreams, which is due out later this year. For more on Tainted Dreams or to watch the first three episodes, click here.
Livingston will make her first appearance on March 18, and is scheduled to appear in two episodes.
