Pop punk Charli XCX's panic attacks almost cost her the chance to work with top hitmakers Benny Blanco and Cashmere The Cat when she dived through a window to escape a meeting.

The Boom Clap singer reveals she was working through new music with the duo when she lost her cool.

She tells Rolling Stone, "I was in the studio with Benny Blanco and Cashmere The Cat (and) I basically ran out through a window on the first floor and dragged half the blinds with me.

"It was either that or walking past them and having to endure a really long conversation about why I was freaking out, so I was like, 'Window it is!'"

The singer has got a handle on her panic attacks but even she admits she's the most awkward pop star: "I'm not supereasy to talk to a lot of the time. I'm just kind of weird."
