The US reality star dubbed her lavish weekend party KhloeWood, in a nod to country star Dolly Parton’s Dollywood theme park.
Rapper Snoop Dogg gave a surprise performance.
Khloe wrote on Instagram: “Deeply Grateful For Every Moment.
“I am so excited and thankful for this fresh decade and all it has in store!!!”
Earlier, on her way to the event, The Kardashians star filmed herself in the car, capturing her see-through top lined with sparkly crystals and diamond jewellery.

She kept her long brunette locks flowing straight down, which she later topped with a cowgirl hat.
Sister Kim Kardashian, 43, dressed similarly to her little sister, and Kourtney Kardashian, 45, and Kylie Jenner, 26, also got the memo and wore all denim.
EPIC BIRTHDAY BASH
Khloe recorded her party’s extravagant entrance, featuring a giant sign of her name, lights around the entryway, and a desert scene with fake cacti and tumbleweeds.
She then gave her followers a glimpse inside before guests arrived, with the bar area completely transformed to look like a saloon.
There was also a giant stage where a DJ played music, a dancefloor, and customized cocktails named after the birthday girl.
Other photos Khloe shared showed guests riding a mechanical bull, a special performance by Snoop Dogg, and exotic dancers on stripper poles.
