Jennifer seems to talk to Brittany Matthews, but it's unsure if they are friends. It is also unkown whether she is on the cheerleading squad. Jennifer McMenamin has known to be trusted around Overland Park because she has not told a lie since the 3rd grade. She also says that Saison Marguerite is from Montreal, but this has yet to be confirmed.
Jennifer was first shown in a flashback to a Mackenzie's New Year's Eve party in 2012 where she was voiced by Jason Earles (of "Hannah Montana").
