Up and coming rapper Lil Peep was found dead on

Up and coming rapper Lil Peep was found dead on his tour bus Wednesday night shortly before his show at The Rock nightclub in Tucson, Arizona was set to begin. Lil Peep, whose real name is Gustav Ahr, was just 21-years-old. Police believe Ahr overdosed on Xanax.

"I am shocked and heartbroken. I do not believe Peep wanted to die, this is so tragic. He had big goals and dreams for the future which he had shared with me, his team, his family and his friends. He was highly intelligent, hugely creative, massively charismatic, gentle and charming. He had huge ambition and his career was flourishing. I have spoken to his mother and she asked me to convey that she is very, very proud of him and everything he was able to achieve in his short life. She is truly grateful to the fans and the people who have supported and loved him," says First Access Entertainment CEO Sarah Stennett. 

Come Over When You're Sober, Ahr's debut album, was released on September 1.
