Belle

From Muppet Wiki

Belle is a figure from Scrooge's past in The Muppet Christmas Carol. A friend of the Fozziwig family, Belle first meets the young Ebenezer at the annual Christmas party. The two fall in love and become engaged. However, the relationship is ruptured by Scrooge's increased focus on business, as the wedding date is continually put off. Belle leaves Scrooge, explaining her reasoning through the song "When Love Is Gone".
