"Sexy when I was younger always meant boobs, and I've never had boobs in my life, so I always felt that sexy was out of the question for me," the Scream 4 star tells Seventeen's May issue. "I used to really want to be that kind of voluptuous girl, and I've just kind of embraced that I'm not."
Turning 20 in February helped Roberts realize something else, too: "I want to be young and have fun."
"Now I just feel content, and I feel like that's a nice place to be," Roberts adds. "I've learned that I want to have great people in my life and lots of love in my life, and just enjoy it. I wish I had realized that sooner."
