Justin Bieber -- I'm Not Banging Hailey Baldwin Or Kendall Jenner

Justin Bieber is not shtupping the young women everyone thinks he's shtupping.

Hailey Baldwin and Kendall Jenner have been hanging with Biebs for a while now, and on the surface it looked like the chumminess was more than friendship. Turns out that's all it is.

As we reported, Bieber has been changing things up ... he hasn't been in trouble for months, he's not hanging with his old crowd and he's spending a lot of time on self-improvement.

Our Bieber sources say J.B. likes hanging with Hailey and Kendall because they're relatively drama free and positive. They go to church, restaurants, concerts and clubs, but it's not romantic.

The trio went to the Clippers game Thursday night, along with 3 Vine stars -- King Bach, Curtis Lepore and Nash Grier.

The trio went to see Bieber's pastor Judah Smith speak on Wednesday night and they hit up a comedy club afterward.

We're told Bieber's not with Selena either -- they see each other, but they're not a couple. Fact is ... he's single, and pretty happy.
