|“||Hey there, Gru. Mr. Life of the party!||”|
Jillian is a neighbor of Felonius Gru.
She has short blonde hair and wears a white zig-zag shirt with blue jeans.
At Agnes' birthday party, Jillian tries to get Gru to date Natalie. Due to her annoyance, Gru sprayed her with water. Later on, she goes to Gru's house to try and hook him up with her friend Shannon. Gru, panicking, tells Agnes to tell her he isn't home. This plan is foiled when Agnes mistakes Gru's various actions for the wrong things. Consequently, Jillian figures out he is actually home, thus forcing him to go on a date with Shannon.
Shannon and Jillian attends Gru and Lucy's wedding.
