Drake used A.I.'s version of Snoop Dogg and 2Pac to diss Kendrick Lamar on "Taylor Made."

Snoop Dogg more or less approved of the move.

For all we know, Pac would have, too.  But we don't know because he's dead.

Pac's estate doesn't approve and has threatened to sue if Drake doesn't take down the track in 24 hours.

The Estate is deeply dismayed and disappointed by your unauthorized use of Tupac’s voice and personality,” estate lawyer Howard King said in a statement. “Not only is the record a flagrant violation of Tupac’s publicity and the estate’s legal rights, it is also a blatant abuse of the legacy of one of the greatest hip-hop artists of all time. The Estate would never have given its approval for this use.”

So far no response from Drake, who's already been threatened by Suge Knight over the use of A.I. Pac.
