MentalJen, also known as UmJammerJenny or simply Jen, is a streamer on Vinesauce and one of the first streamers to join.

Her mascot is a variation of Harley Quinn from Batman: The Animated Series.
Since 2019, Jen's Twitter and YouTube pages were taken down and she has been on a hiatus from social media for reasons not disclosed, but she still remains part of the Vinesauce team.
