Leave it to Taylor Swift, Selena Gomez, Ellie Goulding and the Haim sisters to have the chicest girls’ night in recent history.

The friends spent Saturday night lounging around a Las Vegas hotel room together, sipping on champagne, soda and tea. And of course, it wouldn’t be a girls’ night if they didn’t document it on Instagram:

Well this is bloody CHILL @taylorswift @selenagomez @haimtheband

We are at our best when we cheer each other on and build each other up. Happy International Women’s Day.

Later on, the squad was spotted at Hakkasan nightclub, where Calvin Harris was spinning as DJ. Goulding, who has collaborated with Harris on songs like “Outside” and “I Need Your Love,” joked around in an Instagram caption, writing, “Some random DJ” alongside a snapshot from the show:
