"Nope Knicks coming," one person said.

The photo comes after James’ agency announced Sunday night that he has agreed to a four-year contract with the Lakers.

Klutch Sports Group announced that the contract would pay James, 33, a fully guaranteed $154 million. ESPN reported that the fourth year of the deal was a player option that James can decline in order to become a free agent again after the 2020-21 season.

This is the third time in eight years that James has changed teams via free agency. He left the Cleveland Cavaliers following the 2010 season to go to the Miami Heat. He returned to Cleveland following the 2014 season.
