Rapper and producer Dr Dre is being treated in hospital after suffering a brain aneurysm.
TMZ reports that the 55-year-old was taken to Cedars-Sinai Medical Center in Los Angeles on Monday.
An aneurysm is a bulge in a weakened blood vessel where the blood pressure causes a small area to bulge outwards.
Most brain aneurysms only cause noticeable symptoms if they burst, leading to bleeding on the brain, which can cause a very serious condition and can be fatal.
A post on his official Instagram page has since assured that he was doing well and will be back home soon.
Dr Dre, real name Andre Romelle Young, shot to fame in the late 1980s and early 1990s with the gangsta rap group N.W.A.
He went on to establish himself as a successful solo artist, a leading producer and record label mogul.
He helped to shape west coast rap and was instrumental in the careers stars like Eminem, Snoop Dogg, 50 Cent and Kendrick Lamar.
