Cara Delevingne, the top model turned actress, stopped by The Late Late Show last night to do a bit of press for her upcoming film, Suicide Squad.
While chatting, the always bubbly James Corden asked Cara about the last time she'd pulled a prank on someone.
And apparently, it'd happened very recently, during a visit to Taylor Swift's house over the Fourth of July weekend.
Delevingne concocted a plan to freak out Kesha and the Haim sisters...
...along with the help of Uzo Aduba and Ruby Rose.
According to Cara, they all got flashlights and speakers and made sound effects as a means of frightening their friends.
They really pulled out all of the stops.
