Of all the '00s stars on Snapchat, the "Beautiful Soul" singer definitely lives the most grounded, some might say #basic, life. The once-cute pop star now kind of looks like an aging baby and lives in a suburban subdivision. Luckily for you, we all get to join along on this thrilling ride of post-C-list stardom. According to his Snapchat stories, Jesse spends 80% of his day singing and playing guitar to a room of marginally interested family members and friends, and 20% of the day driving muscle cars. Chic.
