Every time Carly Rae Jepsen performs her disco-pop ditty Call Me Maybe, she thinks she is going to be sick of it.One of the biggest breakout tracks of last year (2012), it topped the Billboard Hot 100 Chart and earned the Canadian singer a Grammy nomination for Song of the Year, reports The Straits Times. With fans demanding to hear it at every live show, it is completely reasonable for the 27-year-old Jepsen to tire of it.But she says she always stops short of feeling that way. "I've definitely heard it and performed it a lot, so every time I perform it live, I think I'm going to be sick of it. But then I see the audience sort of take it over and sing it with me and that always makes it way more fun."Jepsen, a Canadian Idol runner-up in 2007, got her big international break last year when the Biebs tweeted about Call Me Maybe and posted a sing-along video on YouTube with Selena Gomez, Ashley Tisdale and other friends, which later went viral.The video received more than 60 million hits, propelling her to international fame by the time she released Kiss.The star, who says she never tires of being asked about Bieber, says: "I've had an amazing adventure on Justin's Believe Tour and he is totally one of my greatest supporters to date, so I don't ever get tired of acknowledging that, and also thanking him, because he really did change my life and my career."Before Bieber gave her a leg-up in her career, she was a struggling musician juggling eight minimum-wage jobs. She says her rocky road to stardom means she has learnt to appreciate fame and success more than others and that keeps her grounded.Carly Rae Jepsen also made headlines recently when her nude photos were stolen.
