Jessie is a student in South Park Elementary. She first appeared in the episode "Stupid Spoiled Whore Video Playset" as one of Wendy's friends outside of Bebe's group. She was later seen at the Jonas Brothers concert in "The Ring".
Wendy visits Jessie and Kal after she realizes that all of her other friends have become sluts, but is dismayed to find that the pair have also decided to become stupid spoiled whores. Jessie and Kal also introduce the Stupid Spoiled Whore Video Playset to the audience.
Jessie has long blonde hair, worn in a side part with bangs and held back by a green headband (her hairstyle is similar to that of Lola's). She wore a pink sweater with a flower on it, and a dark blue jeans. As a whore, she wore a pink magenta tube top with "SLUT" on it, a denim skirt with a slit up the side, and black high heels with gems on the strap.
She bears a marked resemblance to Lola.
While not acting like a Stupid Spoiled Whore, Jessie appeared to be friendly and amicable. However, when she began acting like a Stupid Spoiled Whore, she appeared to act incredibly superficial, unintelligent and promiscuous.
Jessie and Kal are presumably friends, possibly best friends, as they appear together in "Stupid Spoiled Whore Video Playset". However, they have not been seen together on any other occasions, though this is likely due to both characters' lack of screen time.
Jessie appears to be outside Wendy Testaburger's immediate circle of friends, but they are shown to be friendly. Wendy decides to hang out with Jessie and Kal when she becomes an outsider to her usual group. However, after both begin acting like whores, she decides to leave.
