A Los Angeles judge granted the rapper’s name change request, a communications officer at the Los Angeles Superior Court confirmed to BBC.
The 44-year-old star filed the request in August, citing “personal reasons.
”The rapper, best known for hits such as Gold Digger and Stronger, already used Ye as a nickname and in 2018 used it as an album title.
Shortly after the album’s release, he tweeted: “The being formally known as Kanye West. I am YE.”
Ye explains his name
As well as being a shortened version of Kanye, the new moniker also has religious significance for the star.
“I believe ‘ye’ is the most commonly used word in the Bible, and in the Bible it means you. So it’s I’m you, I’m us, it’s us,” he said in a 2018 interview with radio host Big Boy.
Ye released his latest album Donda in August, featuring 27 tracks with a running time of two hours.
Other artists such as Prince, Snoop Dogg and Sean Love Combs have all changed their names over the years, some several times.
Ye hit the headlines earlier this year after he split up with wife of nearly seven years, Kim Kardashian.
The couple, who have four children together, are among the most recognisable stars in the world.
Their marriage was one of the most closely followed celebrity partnerships of recent decades.
