Russian-born billionaire Len Blavatnik is close to snapping up Warner Music Group in a deal that values the company at $3.3 billion, The Post has learned.

Blavatnik, who already owns a 2 percent stake in Warner, is a board mem´ ber as well as a close friend of Warner CEO Edgar Bronfman.

Blavatnik is said to be the most knowledgeable bid´ der about how to position Warner for future growth.

Sources said Blavatnik’s bid is well above the next closest offer. The Post reported this week that the auction for Warner had come down to Blavatnik and two businessmen brothers, Tom Gores’ Platinum Equity and Alec Gores’ Gores Group.

A spokesman for Blavatnik had no comment, and a Warner spokesman declined to comment.

The board has yet to meet to decide the fate of the firm and insiders cau´ tioned that any deal could still fall apart.
