Canadian pop star Justin Bieber has struck a deal to put his music under the ownership of Hipgnosis Song Management, an investment entity backed by Blackstone Inc.

Hipgnosis bought publishing copyrights, master recordings and neighboring rights for Bieber’s entire back catalog, which includes more than 290 titles released before the end of 2021, Hipgnosis said in a statement Tuesday.

Hipgnosis didn’t provide financial details. Representatives for Bieber didn’t immediately respond to a request for comment. Bloomberg reported in December that Bieber’s stake could fetch about $200 million.

“This acquisition ranks among the biggest deals ever made for an artist under the age of 70,” Merck Mercuriadis, the founder and chief executive officer of Hipgnosis, said in the statement.

Blackstone partnered with Hipgnosis in 2021 and vowed to commit an initial $1 billion to launch a private vehicle called Hipgnosis Songs Capital to acquire music rights and manage catalogs. Kenny Chesney, Leonard Cohen and Justin Timberlake are among other artists whose work has been purchased by Hipgnosis and Blackstone.

The transaction was earlier reported by the Wall Street Journal.
