Discussing her popularity with paparazzi, she said: ''I look uncomfortable because I am uncomfortable. But then it's like, is this person in my life worth that? And he is, without question ... In comparison to how happy I am. And how I feel with him. It's 100 percent worth it.

''That side of my life [the paparazzi] is nothing to do with me. That's, like, that is the ... side of life of the man that I love. And ... when that started happening I had to."
