Selena Gomez—actress, singer and half of pop’s newest power couple—shows off her favorite beauty looks and talks about her transition to grown-up glam in the September issue of Glamour.

On dealing with the rejection of showbiz

“When I was 11 years old, I had a grown woman who was a casting director tell me I was not strong enough to carry the lead in any project. Now I’m doing things that I love, and I’m working really hard. I never want to play the victim or anything, but of course everybody deals with it.”

On being young and in Hollywood

“You have this pressure to fit in and you want people to like you. I try my best to be a good person and be the best I can be.”

On her visible Facebook and Twitter presence

“I love that I can stay connected with my fans and be able to tell them what’s going on—their opinions are so important to me. But at the same time, it’s very weird. I think the Internet can be a great thing but also really evil. Something can instantly hurt your feelings.”

On the media attention that comes with dating Justin Bieber

“I’m 19, so I feel like everything that I’m doing right now should not be taken too seriously. I should be able to have fun and enjoy where I’m at! So I don’t want to spend my time hiding or worrying about all of that.”
