reality tv kris jenner kylie jenner jusitn bieber concert staples center You let your daughter out of the house like this, Kris Jenner?!

Kylie Jenner hit up the Justin Bieber concert at Staples Center last night with her momager, and the 15-year-old was definitely not dressed her age in red leather pants, a see thru tank top and a visible lacy bra. She must be learning how to grab people's attention from her older sister Kim Kardashian!

The Keeping Up with the Kardashians star is rumored to be dating Australian singer Cody Simpson, who happened to perform along with The Biebs last night, so we would bet Miss Kylie went backstage. Ahh to be young, rich, and rubbing elbows with the world's biggest teen pop stars!

Chord Overstreet, Real Housewives of Beverly Hills star Kyle Richards, Jason Bateman, and others also came out to watch JB bust a move.
