Kelsea Ballerini and her crew took to Vegas for her Bachelorette party over the weekend.

What happens in Vegas stays in Vegas right...not if you are addicted to social media!  The girls got hooked up with some tickets to go see the Jennifer Lopez show and Kelsea posed with her after the show.  J Lo was nice enough to pose with the whole crew individually!

It looks like they had a great time and we have the Instagram posts to prove it!  From the whole crew in swim suits, a selfie with J Lo, a video with Kelsea hamming it up in the plane aisle, to Kelsea eating a burger at a driving range while enjoying a's all here!
