Philadelphia 76ers rookie center Nerlens Noel had no problem admitting to our photog he listens to Justin Bieber's music, but telling his teammates ... might be a different story.
Noel was in Midtown Manhattan when he volunteered that Bieber is his favorite celebrity baller, and he even copped to liking a few songs ... at home.
Which is probably good. Even better -- the other pop star he reveals is DEFINITELY persona non grata.
The Sixers don't win many games, but at least they don't play crappy music.
