During her sister Khloe Kardashian’s 40th birthday celebration on Saturday, Kylie Jenner displayed her wild side. 

The 26-year-old beauty mogul shared amusing videos of herself and her best friend Stassie Karanikolaou riding a mechanical bull at the lavish party with a Dolly Parton theme on Instagram.

Kylie and Stassi wore amazing “diamonds and denim” themed ensembles in the long film, which featured the antics of Khloe, Kim Kardashian, and grandma Kris Jenner, before getting on the bull.

After getting saddled up, Kylie stands in front of Stassi, and the two laugh heartily as they get whirled about on the machine. 

Given that Timothee Chalamet and Kylie were spotted on a romantic date the night before, it was unclear if he participated in the exuberant celebrations. 

The actor from Dune, 28, and the reality personality, who was last seen together at the Golden Globes in January, kept low profiles as they arrived at the TCL Chinese Theatre for a movie night.

The mother of two wore a white crop top and black loose leggings, accessorising with a facial mask and baseball cap to accentuate her toned stomach.

She went ahead of her matinee idol lover while sporting a black jacket, a big black purse and basic flip-flops to finish off her ensemble.

Timothée added his own personal touch to her chic, dark ensemble by dressing in a face mask, relaxed shorts, a casual baseball cap, and a sleek black sweatshirt. 

The couple’s outing comes after their May double date in New York City, during which they were not captured on camera. 

According to People, Kylie and Timothee went to the hotspot known as Tatiana by Kwame Onwuachi and joined another pair.

An insider told the magazine that Timothee was “really chill and so nice” at the informal supper during the enjoyable occasion.

Both Jenner and Chalamet, according to a different source, wish to keep their connection “low-key” and primarily hidden from the public.
