Jeannie is a average teenage girl, babysitter and student who babysits George and Joan's Baby in the Tom and Jerry MGM shorts: Busy Buddies and Tot Watchers. She is voiced by Janet Waldo. She has appeared again on Tom and Jerry Tales in Babysitting Blues. She's been voiced by Grey DeLisle since 2008.
Jeannie's a fair-skinned blonde with hair tied back into a ponytail with a blue bow with her bangs hanging down. She also wears a pink blouse with a burgundy skirt and black slip-on shoes.
Jeannie's also not a very good babysitter, because while the baby's parents are out, she regularly relies on the telephone rather than doing her actual babysitting, and Tom and Jerry are shown to be better babysitters than she is.
When the baby crawls out of his bed in Busy Buddies and Tot Watchers, Tom and Jerry both do their best to bring him back home and put him in bed, but Jeannie claims that the two were bothering the baby, and she'd hurt Tom with a broom.
Despite her sub-standard babysitting skills, Jeannie's very kind and friendly and has many friends in high school. Her least favorite and weakest subject is apparently algebra, but she wants to do well in that particular class. In her final appearance, she eventually called the police so they can arrest Tom and Jerry whom they both claim to be "babynappers," until it was discovered that the baby started crawling out of the house, where she could eventually take the blame or not.
Jeannie has friends from high school, but only mentioned during dialogue on the telephone. Her friends include Mike, Gary and Jane.
