'Good For You' songstress Selena Gomez has opened up about the moment she put getting over her split from Justin Bieber to bed in a new revealing interview with ELLE magazine.

The beauty explained that her emotional performance of 'The Heart Wants What It Wants' at last year's American Music Awards was that exact moment for her:

"Everybody was talking about the same thing: my relationship. I was so exhausted. I said, 'I want this [performance] to be the last time I have to talk about this. And acknowledge this feeling.' I was kind of devastated. I was like, 'This is all I have right now. This is gonna be it. And all I want is to move on'."

She went onto add that once it was over, she felt incredibly relieved and has now been able to move forwards with her life: "It was a huge weight lifted off me. That's why, from this point on, I know I can prove myself, you know. I haven't scratched the surface yet."
