Barack Obama LIED to Jimmy Kimmel -- at least that's what Kanye West says -- but the rapper insists he's got nothing but love for the Prez.

Kimmel asked Barack Thursday night if he ever called Kanye at home -- something the rapper recently claimed. The Prez said, "I don't think I've got his home number."

But we got Kanye at LAX Friday ... and the rapper squared off with O -- reiterating that Obama has called Kanye's home.

And there's this ... What the hell happened to this guy??? He's becoming the nicest celeb in La La Land.
