Nick Young -- 'I'm Killin' It Right Now!'

It's good to be Nick Young right now … and Nick Young knows it.

The Lakers star was out in L.A. this weekend … when he told us himself, "I'm killin' it right now."

He's right.

But besides the fact he's got a smokin' hot rap superstar GF and a huge NBA contract on the horizon … Nick says there's one more thing he's after -- Harvey Levin's job.
