Annabel Foster is Tom Scavo's ex-girlfriend.
Lynette is extremely jealous of her and has been doing anything she can to break her up from Tom. Annabel explains to Lynette she has no interest in getting back together with Tom, although when offered a work position in Hawaii, she chooses Tom to accompany her, separating him from his family even further. She gets the promotion of vice president which Tom was eyeing, which leads to Tom quitting his job.
- She had no relation with Melanie Foster as far as we know, except that they both lived in Chicago.
