Jennifer Lopez celebrated her 47th birthday in Las Vegas this weekend and had her celebrity pals on full tilt for the occasion. So much went down at the bash, which took place at the Aria hotel, that we don't know where to start. 
First of all, Taylor Swift's worst nightmare came true: Her nemesis Kim Kardashian was spotted hanging out with her bitter ex Calvin Harris, and they certainly looked as if they had a lot to talk about. Hopefully they weren't plotting another takedown of America's former sweetheart.
Speaking of being newly single, Iggy Azalea also reportedly hooked up with French Montana at the event. Wonder how the rapper's rumored boo Sanaa Lathan feels about that?

LaLa Anthony seems like she had a great time:

Kim Kardashian brought the cake, which she says was "really heavy." Calvin Harris and French Montana were also on hand to help blow out the candles.

The outer boroughs were representing in full effect. Fat Joe and Fabolous held it down for NYC:

And here's J. Lo's outfit in full — a Balmain jumpsuit that shows off her toned body to perfection. This is what 47 years old looks like:

Ultimately, nobody had a better time at the bash than J. Lo herself. Turn up, girl!

From the looks of it, Jennifer is having a better time at 47 than most of us did at 27. Happy birthday once again!
