Cara Delevingne, Ruby Rose, and Uzo Aduba terrified Kesha and Haim at Taylor Swift's 4th July party.

The 'Suicide Squad' teamed up with the 'Orange is the New Black' actresses to form the ''Ghost Crew'' and went ''full in'' to scare their pals, who had spent the day watching murder mysteries.

Cara told 'Late Late Show' host James Corden: ''They were all in this creepy area of the house. They were watching murder mysteries all day. We got torches, speakers, we did sound effects. We were going to do rocking chairs with bits of thread outside. We went full in.''

The infamous 'squad' of Taylor, Cara and their pals are incredibly close and Karlie Kloss recently credited them with helping them be more confident.

She said: ''I grew up being the tallest in my class and was always teased for being skinny. Whether it was because of those people at school or people online now, I had to develop a thick skin.

''You have to learn to cope with people's opinions - it is so important for women to be surrounded by people who truly support them. You have to have a core support group.''

Despite accusations the group is elitist, Karlie insists her friends are all very ''kind and caring'' and she loves the fact they will always try and make time for one another, no matter how busy their schedules are.

She shared: ''My friends are kind, caring, thoughtful people. I think that's what draws everyone in the group together. We are all very supportive of each other. We're a big network of really great friends who all have very international schedules and lives. We try to get together as much as possible, even if we're all travelling in different places.''
