Carly Rae Jepsen is being sued over "Call Me Maybe."

A Ukranian singer, Aza, is filing a lawsuit in Los Angeles, claiming the Canadian star's mega hit copies her track, "Hunky Santa." The lawsuit claims the festive themed song - recorded in English - has the same lyrical basis as Carly's track, and was taken without consent.

"I'm shocked and surprised that these people wanted to sample my lyrics on their song. They didn't ask me for permission, they just took it. That's why I filed this lawsuit. When I first heard it on the radio, I was driving and almost got into an accident. I couldn't believe what I was hearing," former Miss Ukraine Aza told TMZ.com.

The lawsuit is seeking substantial damages to compensate Aza.

Representatives for Carly, 26, deny her track is in any way related to "Hunky Santa." A representative said, "This is completely false and Carly's lawyers will deal with this. Everyone knows Carly is a songwriter. She is not spending a lot of time listening to Ukrainian radio."
