Totally not sounding politically correct here but....
Which sister is he banging?!
Justin Bieber had a long night out with Kourtney Kardashian last weekend, when they partied at The Nice Guy in West Hollywood, before retreating to Justin's hotel until 4AM.
Justin returned to Nice Guy last night....except this time?
With Kendall Jenner!!
Sources say the two arrived separately, and left separately, much like Biebs and Kourtney did. Little did we know until later, that she had met up with him at his Beverly Hills Hotel.
Now, Kendall and Bieber have been friends for year, so maybe he's getting pointers on how to score with her bigger sister?
