(CNN)Rapper DMX remains hospitalized and on life support in White Plains, New York, his longtime attorney Murray Richman confirmed to CNN on Sunday.
The rapper suffered a heart attack Friday around 11 p.m. at his home in White Plains and was taken via ambulance to a local hospital, where he remains on a ventilator, Richman said. The attorney said he did not know what may have caused the heart attack.
Richman said he has known DMX for 25 years and said Saturday evening that he has been in touch with the rapper's family all day. He said he is aware of the rapper's medical prognosis, but declined to comment on it.
"We ask that you please keep Earl/DMX and us in your thoughts, wishes, and prayers as well as respect our privacy as we face these challenges," the rapper's family said in a statement.
DMX, whose real name is Earl Simmons, burst on the rap scene in the late 1990s with songs including "Party Up" and "Get At Me Dog." His first five albums debuted at No. 1 on the Billboard charts. The 50-year-old is also an actor, and IMDb lists more than 40 acting credits for him. His roles in "Romeo Must Die" -- which starred R&B star Aaliyah just before her death -- and "Never Die Alone" are among his most notable, and he often appeared as himself in films and TV shows.
DMX has received three Grammy nominations, all of which came in either 2000 or 2001. Two were for Best Rap Solo Performance and the third was for Best Rap Album.
Some of DMX's contemporaries, such as LL Cool J and Missy Elliott, tweeted their prayers, as did more artists, including Chance the Rapper, Kid Cudi, Eminem and SZA.
