Lotto (Jessica Smith) is the secondary villainess from the 2018 Lifetime film, Killer Twin (alternately titled, A Sister's Obsession; airdate August 4, 2018). She is the best friend and roommate of the film's main villainess, Amber Sheridan.
Lotto's backstory was never revealed, though it can be assumed that she has played a role in Amber's criminal history. She was stunned when Amber told her that she had a twin, and she even assisted Amber in her plan to become Kendra. Lotto hacked into Kendra's bank account, allowing Amber easy access to steal Kendra's money.
Throughout the movie, Lotto took notice of the fact that Amber was plotting to kill Kendra and take over her life, but notably only showed concern over the possibility that Amber's actions (including murdering Kendra's friend, Monica Lawrence) could result in them facing extensive jail time. Lotto later helped Amber during the final piece of her plan by hacking into Kendra's emails, as Amber planned to take Kendra's place at an award ceremony. Amber had stolen Kendra's valuables from her deposit box, and it was stated that the valuables would be used to finance Lotto and Kendra's escape. Though Amber ended up arrested, Lotto's fate was never revealed in the film.
