Missy Elliott, Sean “Diddy” Combs and Snoop Dogg are among stars urging fans to “pray” for the rapper Rick Ross, who has reportedly been hospitalised and put on life support after suffering a heart attack.

Ross was hospitalised early Thursday morning after he was found unresponsive in his Florida home by police and emergency teams, according to Billboard.

An ambulance took the 42-year-old Florida native to a hospital, where he was treated for respiratory issues.

Officials told the Blast they considered the call serious because Ross has a history of seizures, and a 911 caller said that Ross was just “nodding his head.”

TMZ is reporting that Ross is being treated in the hospital’s cardiac unit.

Doctors are reportedly treating him with extracorporeal membrane oxygenation (ECMO), a form of life support in which blood is oxygenated outside of the body before it’s pumped back into it.

The musician and entrepreneur has received the support of his famous friends on Twitter, including many in the hip-hop world. Elliott wrote: “I BELIEVE in the Power of Prayer. Sending Prayers up for Rick Ross.”

Combs said: “Let’s all pray for Rick Ross.” Snoop Dogg said he was praying for “my guy Rick Ross” and added: “Hope you pull thru my brotha.”

“Everyone pray for my buddy RickRoss to get well soon!” rapper Gucci Mane wrote.

The actor and comedian Martin Lawrence tweeted: “Prayers up for Rick Ross and his family.”

The rapper Fat Trel, who is signed to Ross’s record label, said Ross was “good” and was not on life support. He posted on Instagram: “JUS TALKED 2 MY BIG HOMIE... HE GOOD... HE IN DA HOSPITAL BUT HE IS NOT ON “LIFE SUPPORT” ... HE GOOD.”

Ross, whose real name is William Leonard Roberts II, suffered two seizures within the space of six hours in 2011.

A representative for Ross did not immediately return a request for comment.
