Pop star Selena Gomez has had enough. She's tired of being constantly linked to her ex-boyfriend, and she's really tired of constantly being referred to as "Justin Bieber's girlfriend."

According to a source, 22-year-old Gomez, who dated Bieber, 20, on and off for the past three years is completely fed up with people mentioning her and Bieber in the same breath, reports hollywoodlife.com.

"Hearing that she is with Justin and should be with Justin or shouldn't be with Justin is exhausting," the source stated.

"She always reads about herself and Google's herself and she hates being known as Justin's girlfriend or not his girlfriend. She wants to be known in her eyes and to others as Selena Gomez."
