Pop singer Avril Lavigne can`t live without a black eyeliner because she is in the habit of wearing it everyday.
"The thing that I am most addicted to is black eyeliner. It`s been my obsession for years," said Lavigne.
"I feel like my style has evolved since I was 17 years old and I`m 25 now. I`ve changed fashion-wise which is normal to do," she said.
