Shannon Bell was a former lover of Lex Luthor.
Scorned by Lex, she was given diamond earrings by Lex to leave him alone after their affair. Thinking that she and Lex had a real relationship, she risked everything that she had, including her fiancé, and lost it all. Shannon was also ignored by Lex when conversing with her boss, Corrine Hartford. She planned to frame Lex into getting what he deserved.
She killed another one of Lex's former lovers, Eve Andrews, framed Lex for the murder, and killed Corrine to lure him to her. She captured him and was determined to kill him by setting him on fire, but her plan failed when Clark Kent saved him. She was knocked out by Clark and later taken to prison.
