Kanye West and Bradley Cooper have topped Time magazine's 100 most influential people in the world list.
West was described as a boundary breaker and pop-culture juggernaut by entrepreneur Elon Musk, who penned an essay on the 37-year-old for the special issue.
"Kanye West would be the first person to tell you he belongs on this list," Musk wrote.
"Kanye's belief in himself and his incredible tenacity - he performed his first single with his jaw wired shut - got him to where he is today."
