Jenna got her start on Barstool Sports, writing on their sister site StoolLaLa, but she blew up when she made the video "How To Trick People Into Thinking You're Good Looking," which has more than 60 million views alone. That was followed up with "How To Avoid Talking To People You Don't Want To Talk To," which has 34 million views. She's funny as hell, makes fun of herself and the things girls (and sometimes guys) do, and these types of videos helped ignite her way to more than a billion views in all.

Sidenote: she got the name "Marbles" from her dog.
