The 55-year-old hip-hop legend suffered the aneurysm on Monday, Jan. 4 and remains in the ICU at Cedars Sinai Medical Center in Los Angeles. The California Love performer is stable, but doctors are uncertain of what caused the brain injury and are administering numerous tests, according to TMZ. A number of the star's famous friends and collaborators shared their support on social media. This comes at a difficult time in the star's life when wife Nicole Young filed for divorce in July last year following 24 years of marriage, citing irreconcilable differences. Dr Dre took to Instagram recently to let everyone know that he is on the road to recovery. "Thanks to my family, friends and fans for their interest and well wishes," he shared adding a throwback photo of himself at a mixing board. "I'm doing great and getting excellent care from my medical team. I will be out of the hospital and back home soon."
