Rapper Lil Peep has died at the age of 21, his UK publicist has confirmed. According to the Guardian, Tucson Police Department said that there was evidence of a possible drug overdose, but there hasn't been any official word yet.

Lil Peep, born Gustav Åhr, was found unresponsive in his tour bus. His manager, Chase Ortega, tweeted last night that he had been "expecting this call for a year." He has since made his Twitter private.

After self-releasing a series of mixtapes on SoundCloud, the Long Beach, New York-based Peep quickly gained recognition as an “emo rapper” because of his highly emotional lyricism. Lil Peep’s music was candid and open about his struggles with anxiety and depression, and mixed elements of rap, emo, beach pop, and more to create his unique sound.

His recent tracks off of his debut studio record, Come Over When You’re Sober, Pt 1, have racked up millions of views on YouTube. The album, which dropped in September, only had seven songs, which has led many to believe he was working on a part two with other notable rappers and producers like Post Malone.

Peep’s style and tattoos also led him to find success in the fashion world—he was recently in a V magazine editorial and walked in runway shows such as Vlone's Paris Fashion Week show.

Artists like Diplo and Marshmello have tweeted their condolences about the rapper’s passing:
