Dr Dre is in the ICU after suffering a brain aneurysm, according to TMZ.
The rapper and record producer, who is 55, suffered the aneurysm on Monday and was rushed to Cedars Sinai Medical Center in Los Angeles, sources told the website.
Doctors say they don’t know what caused the bleeding but are performing a series of tests to uncover the cause.
High blood pressure is the leading cause of a subarachnoid haemorrhage and heavy lifting or strain can cause the aneurysm to rupture.
Fellow N.W.A. member Ice Cube took to Twitter to offer good will: ‘Send your love and prayers to the homie Dr. Dre,’ he wrote.
The megaproducer also co-founded the Beats by Dre empire with Jimmy Iovine and helped launch and run Death Row Records. Dr. Dre’s many producing credits include Eminem, Tupac Shakur and Snoop Dogg.
After coming up with N.W.A., Dr. Dre’s debut album, The Chronic in 1992, made him a music superstar.
The Compton, California, native later branched out to become a music mogul worth nearly $1 billion.
The popular rapper is currently embroiled in an ugly divorce months after his estranged wife, Nicole Young, filed to legally end their marriage on the grounds of irreconcilable differences.
She is seeking nearly $2million in monthly spousal support payments and $5 million for attorney fees from Dre’s estimated $1 billion business empire.
