Demi Lovato hits the red carpet at the celebration of her Nylon Magazine December 2013/January 2014 issue on Thursday (December 5) in West Hollywood, Calif.

The 21-year-old singer and X Factor judge was joined at the party by her ex-boyfriend Joe Jonas, who was sporting one mega mustache that night. He happens to have a feature in the new issue of Nylon Guys!

Joe recently wrote an article for Vulture in which he revealed that he first smoked weed with Demi and Miley Cyrus nearly six to seven years ago.
