Kylie Jenner attends a cowboy birthday bash

Kylie Jenner helped one of her closest friends, Victoria Villarroel celebrate her cowboy birthday bash.

The beauty mogul and youngest billionaire took a night off mom duty with sister Kendall Jenner, Winnie Harlow, Diplo, and more to party it up.

Kylie dedicated a sweet message to Villarroel on her Instagram Story saying, "Thank you for your infectious energy, beautiful friendship and memories. You’re a REAL ONE!”

Villarroel has been a long-time member of the Keeping Up star's inner circle, working as Kylie's personal assistant.

Last year however, Villarroel quit to dedicate her time to her own path in life, starting her Girl Cult podcast.

In response to rumours of drama between the girls, Villarroel wrote on her Instagram that, “I worked with Kylie for 5 years and she became one of my closest friends. We both decided it was time to grow without each other professionally about a year ago!"

"She’s still one of my best friends and our relationship has only gotten stronger,” she continued. “Now let’s focus our time and energy on other things!”
