The actress has been documenting her friend-cation in Sin City on Instagram, and it's making all of us envious.
The trip comes days after Barrymore's divorce from Will Kopelman was finalized. The couple, who have two daughters together, was married for four years before announcing their split in April.
Barrymore, 41, hopped on a private jet with six friends to start her trip. She captioned a photo of the group: "Is this bird going to Vegas? If so yay!!!#Vegasbaby #besties #lifelongers #oldschool."
Next up, the crew hit the Pole Position Raceway to go indoor go-kart racing. The actress proudly posed in one photo wearing a silver helmet.
After all the running around, Barrymore and her friends enjoyed a visit to Lotus of Siam restaurant.
"Everyone has just been so cool and chill and nice about everything that it quelled my own fears and demons about how we sort of have to go through things in life," she said.
