Taylor Swift and Zayn Malik trashed a hotel room and started a fire for their sexy new video

Zayn Malik and Taylor Swift trashed a London hotel room while filming a sexy video for their new single.

The former One Direction star smashed a lamp against the wall of the five-star St Pancras Renaissance hotel and Taylor, 27, set the curtains on fire as they filmed the video for their single I Don't Wanna Live Forever, which features on the soundtrack for Fifty Shades Darker.

A source shared: "Zayn trashed the hotel room to bits, ripping apart pillows and smashing a lamp up against the wall.

"All the scenes were carefully planned. It's going to be a very sexy video. Zayn was dressed dapper and Taylor was wearing garters and heels."

Taylor flew into London from Nashville in the US via a private jet to shoot the video, but quickly returned home after filming was concluded.

The source told The Sun newspaper: "She flew straight back to Nashville and left him alone."

Last month, meanwhile, Zayn revealed his girlfriend Gigi Hadid helped set up his collaboration with Taylor.

The 23-year-old star asked Taylor to sing on the track - but he wasn't nervous about her agreeing to be part of the song because he knew she already liked it thanks to model Gigi.

He shared: "The interesting thing was, she is friends with Gi, so she already reached out after hearing it because [producer] Jack [Antonoff] had just played her the song anyway and she went in the studio the next day to record it.

"She mentioned to me that she liked the song so I already kind of knew in the back of my head that she liked it, so I asked her if she wanted to be on it and she was cool with it."
