(Photos)Girls Night Out! Selena Gomez, Kylie Jenner, Kendall Jenner, And Khloe Kardashian All Go Partying Together!

Selena Gomez seems to be taking her friendship with the Jenners to a whole new level. First she was seen having a lunch date with Kendall Jenner last month, and now it seems that she's become friends with the whole Kardashian clan, as she had a girls night out with Khloe, Kylie and Kendall yesterday as well.

The girls all headed out to 1 Oak in West Hollywood on Friday night to celebrate the 16th birthday of Christian "King" Combs, the son of P. Diddy.

They all took to their instagram to share some of the best moments of the night, which included selfies on the dance floor.

The party had an all-black dress code, so all of the ladies did their best to look elegant in black.

Both Selena and Kylie took to their instagram to post the same image of the two of them lying on a surface with roses. They seemed to have planned their instagram posts together as Kylie wrote "Selena&Roses" on hers, while Selena wrote "kylie&roses" on hers.

Big sister Khloe Kardashian seemed to spend more of her time with others at the party, as she was not pictured in these intimate images.

Others who attended the party included French Montana, Meek Mills, Kendrick Lamar, Zendaya, and Willow Smith.

Khloe has also been linked to rapper The Game in addition to French Montana.
