She said that Taylor's I Knew You Were Trouble was how she first learned about hitmaker Max Martin, whom she eventually hired for Send My Love.
"I was in New York, writing Remedy with Ryan Tedder. We were having lunch and I Knew You Were Trouble came on the radio - Taylor's song that she did with Max and Shellback," she recalled. (Also Read: When the 'Adele Lookalike' at an Audition Turned Out to be, Well, Adele)
"I was like, 'Who did this?' I knew it was Taylor, and I've always loved her, but this is a totally other side - like, 'I want to know who brought that out in her'. And he said (Swedish music producer) Max Martin," she added.
Adele said that she was unaware that who Max Martin was. "I Googled him and I was like, 'He's literally written every massive soundtrack of my life'."
She then contacted Martin through her management team. "They came to London and I took my guitar along and was like, 'I've got this riff', and then Send My Love happened really quickly," she said.
"Max Martin, I could just hang out with him forever. He's so beautiful and lovely and funny and generous and warm and caring. He's a really amazing man," said Adele.
