The 27-year-old singer teamed up with the 'Pillowtalk' hitmaker for 'I Don't Wanna Live Forever' from the 'Fifty Shades Darker' soundtrack and gushed about his "really rare voice" and "amazing" talent.

In a behind-the-scenes video from their music video obtained by Capital FM, she said: "I've known Zayn for a really long time. I think his voice is one that is really rare and I think he's really special and wonderful.

"It's really, really amazing to get to work together. It's amazing when you get to work with people who you hang out with. The question of, 'Will we get along?', is already answered. We know we get along like, 'Yeah it's fine.'"

The pair recorded the video at the five-star St Pancras Renaissance hotel in central London, where they reportedly "trashed the hotel room".

A source said: "Zayn trashed the hotel room to bits, ripping apart pillows and smashing a lamp up against the wall. Taylor had to light the curtains on fire for her part. The smoke alarms were turned off on the nearby floors so that the building didn't have to be evacuated.

"At one point Taylor smashed a mirror in the bathroom. 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."

Meanwhile, Zayn previously confessed his girlfriend Gigi Hadid set up the collaboration.

He explained: "The interesting this 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."
