Lexii Alijai’s cause of death has been revealed.

The 21-year-old rapper died last month as a result of mixed fentanyl and ethanol toxicity, the Hennepin County Medical Examiner’s office confirmed to E! News. The manner of death was accidental.

Alijai, granddaughter of the legendary Roger Troutman of the Zapp band, died on New Year’s Day at the age of 21. Authorities responded to a medical situation at a local hotel, where an adult female was found dead.

The Minnesota native rose to fame with her popular remixes of songs by Drake, Tupac, and Nas, and released two projects including 2015’s Joseph’s Coat and 2017’s Growing Pains. She also collaborated with Kehlani on 2015’s “Jealous” off the Grammy-nominated You Should Be Here.

Kehlani paid homage to her friend following the tragic news. “You were so special bro,” she tweeted. “I seen you fight thru it all i seen u thug it out lex imma miss you so bad. You was about to get everything you always talked about. RIP MY BABY I LOVE YOU LEX 4L.”

Others including Ella Mai, Ari Lennox, Wale, Russ, and Bas also penned tributes on social media in the wake of her death.

A benefit concert will be held in Alijai’s honor on Feb. 19 in Minneapolis with a performance from Kehlani and a special guest. A GoFundMe page for a recording arts scholarship has also been set up in her name with the goal of raising $30,000.
