Since playing Alice Cullen in the Twilight saga, Ashley Greene has dated a pop star, traveled all over the world and graced the covers of some of the biggest magazines – but the actress says none of the glitz and glamour has changed her.
“I have the same friends and family and the same kind of foundation that have kept me grounded from the very beginning,” Greene, 25, told PEOPLE at Monday’s Breaking Dawn – Part 1 premiere in L.A. “That’s probably the only thing that hasn’t changed.”
Other things, however, have been altered in Greene’s life since taking on her coveted role beginning when she was 20.
“I’ve learned so much about myself,” she says. “Especially as a woman, I just kind of really am much more comfortable with myself and have more of a sense of who I am and what I stand for than I did when I started.”
As for specific skills she’s gained: “I’ve learned how to multi-task a lot better and I’ve learned travel tricks.”
