UPDATED: French Montana remains in hospital after checking in following an initial report of a robbery at his home, Variety has confirmed. The 35-year-old rapper made the decision to go to the hospital after suffering severe stomach pains, nausea and an elevated heart rate in the early afternoon.

While initial reports said that he was expected to be released soon, a source close to the situation said Friday afternoon that the rapper’s stomach pains have not diminished and he remains under observation by doctors, who are closely watching his heart condition. TMZ, which first reported the news, says doctors are unclear on the nature of Montana’s ailment.

A Los Angeles County Sheriff’s Department representative confirmed that deputies responded to Montana’s home in Calabasas after reports of a robbery in progress but did not find evidence of criminal activity and departed the premises, but decided to call EMT officials after observing Montana’s condition.

Montana — whose real name is Karim Kharbouch — was born and raised in Morocco and immigrated to the United States when he was 13. He recently visited his native country, his Instagram indicates. His most recent album, 2017’s “Jungle Rules,” reached no. 3 on the Billboard Hot 200 and featured the single “Unforgettable,” with Swae Lee, which reached the top 10 on the U.S. Billboard Hot 100.
