While other stars such as Beyoncé refuse to mingle with people like Khloé's siter Kim Kardashian, it looks like Lopez has no problem inviting reality television stars to her birthday. Lopez managed to even pose for a photo that Khloé shared on her Instagram account which she captioned with, "She served it last night!!! Happy birthday @jlo."

Along with Khloé, Kourtney Kardashian's significant other Scott Disick was at the soiree, as well as Khloé's current main squeeze French Montana, Dancing with the Stars pro Maksim Chmerkovskiy and rapper Fat Joe. Other celebrities included Lopez's best friend Leah Remini, Tracy Anderson, Russell Simmons, Andy Cohen, Kelly Ripa, Kristen Chenoweth, Rachel Zoe, Brian Atwood and Lopez's longtime manager Benny Medina.

Meanwhile, it seems as though Lopez has been enjoying her time in the Hamptons as she also recently shared a picture of herself lounging poolside in a bikini. Remini apparently took the photo with Lopez adding the caption with, "She yelled at me "DON'T MOVE!" Another shot by Remini... #shemakesmelaugh #notmad #loca #loveher #shesgettinggoodatthis."

Lopez has taken a quick break from recently promoting her latest album, AKA, which hit shelves just last month.
