Australian folk singer Sia is hurt by Amy Winehouse after the troubled rehab singer told her she was too intimidated by her to team up on record. Sia is a big fan of Winehouse’s music, and approached the troubled singer over a planned collaboration. But she had no idea Winehouse would turn her down flat. Sia says, “I asked Amy Winehouse to do a collaboration and she said, ‘No way.’ And I was like, ‘Why not?’ And she said, ‘I’m intimidated by you. I’ve been listening to you since I was a teenager.’ “I was totally shocked because she’s my favourite contemporary voice.” And Sia admits she’s now become Winehouse’s celebrity ’stalker’. She adds, “I’ve met her a couple of times and I kind of stalk her.”I’ve got her phone number and whenever I listen to her album and I love it, I text her and say, ‘I’m listening to it again, it’s so good!’ She never responds. She doesn’t really respond to anyone, she doesn’t do e-mail.”
