Just this afternoon, Jennifer Lopez posted this tweet on Twitter:

Where is the shining star? At a Justin Bieber concert, of course! And, apparently she’s liking what she’s hearing. The pic shows Jennifer creeping up on the Biebs big-time at his L.A. concert, but, she isn’t the only one!

According to E! Online, Khloe Kardashian, Kylie Jenner, and P. Diddy’s three daughters all made a rather ravishing appearance at the concert. All Beliebers, unite!
