Shannon Bell was a former lover of Lex Luthor in the WB Television series Smallville. She served as the main antagonist in the Season 4 episode "Bound".
She was portrayed by Cobie Smulders.
Shannon Bell was engaged to be married. However, this didn't prevent her from cheating on her fiancé and having a one-night stand with Lex Luthor. Convincing herself that she had a shot at marrying the rich Lex, Shannon dumped her fiancé, only to then be confronted with the fact that her night with Lex had just been a casual fling.
Lex never called her again, but gave her a pair of diamond earrings. Rather than accepting her mistake, Shannon shifted all the blame to Lex and insisted that he had ruined her life.
Consumed with vengeance, Shannon sought to ruin Lex's life. First she arranged for Lex to meet and pick her up again at a fundraiser, while posing as a woman named Eve Andrews who was one of Lex's previous lovers. Afterwards, she killed the real Eve Andrews and left her body in the bed, next to Lex, framing him for murder.
Lex called his lawyer, Corrine Hartford to field the media frenzy while she questioned Lex about the evening. Shannon was Corrine's assistant but since Lex was heavily drinking the previous night he did not recognize her.
Corrine discovered that Eve was stalking him because he slept with her and became obsessed with him. She revealed that Lex also jilted her, and Lex realizes she is the one who compiled the stalker database. Corrine declared that she couldn't be his lawyer because their past relationship was a conflict of interest and left. She murdered Corrine Hartford and left the body for it to be found.
Lex later returned to her office having been summoned by Corrine but when he got there, he found her dead. He calls 911 but finds the pink mp3 player on the desk, playing the same song from the night he met Eve. Suddenly Shannon appeared and asked Lex if he recognizes her. Lex was confused and Shannon knocked him out. She took Lex back to his mansion bound and tied where she reveals that she cheated on her fiancé with Lex because she thought he loved her.
Shannon explained that she met up with Eve, then murdered her, drugged Lex and put Eve's body in the bed next to him to make it look like he killed her. Meanwhile, Clark and Chloe traced the diamond purchase to Shannon Bell and he hurried away to warn Lex. Shannon tied Lex up and was pouring a bottle of wine all over him and the floor, ranting about how Lex slept with her more than once, then didn't even recognize her at the party nor as Corrine's assistant.
She says she's stopping him from doing it again and drops a candle on the floor. The alcohol ignites and the flames surround Lex just as Clark super speeds into the room. He uses his jacket to blow out the fire and knocked Shannon out before super speeding away unseen. Shannon was later taken to prison.
