Jennifer Lopez has a good time with friends at the Aspen Bar, including Kevin Costner

Jennifer Lopez let loose with friends at an Aspen bar on Friday, showing off some big dance moves while sipping drinks.

The singer/actress hit the bar at Kemo Sabe, located in Colorado’s famous ski resort town, on Friday evening – and she was joined by her manager, Bennie Medinaand a few girlfriends, and also Kevin Costner.

Check out photos of J Lo happily chatting and drinking cocktails with her friends.

In the photos, J Lo can be seen with a big smile on her face, pursing her lips, wearing a black cowboy hat and sticking her tongue out. At one point, Costner strolled over to see J Lo and Co hanging out.

We also have a video of J Lo doing some moves for everyone while dance music plays in the background… apparently having fun.

It’s nice to see J Lo in such a good mood after enduring quite a tough year. As we reported… J Lo filed for divorce by Ben Affleck in August and the two are now embroiled in a messy legal battle over their lack of a prenuptial agreement.

Without a prenuptial agreement, everything the estranged couple received during their roughly two-year marriage is community property, meaning assets acquired during the marriage are divided equally. Given all their assets, the process of dividing them fairly is complicated.
