Most people would love the perks that come with being a star of a hit movie, but Ashley Greene of "Twilight" fame admitted in a new interview with Marie Claire magazine that getting the VIP treatment has its downsides.

"'Twilight' has ruined me," she said. When this is all over, flying internationally is going to be very hard for me. It is just not worth it to buy a first-class ticket, because of the cost."

With the end of the "Twilight" saga in sight, Ashley, who plays Alice Cullen, realizes it's important to be smart about her finances.

"I'm lucky because my dad taught me to be frugal and save," she said. "And that's important because I want to know that I don't have to take an acting job for two or three years if I don't want to and that I'll still be able to make my house and car payments and buy food for my dogs."

Ashley told Marie Claire it was "a hard adjustment" when she found herself on the celebrity fast track, especially when it came to talking with friends.

"It was a hard adjustment going from zero to 100 in a day. But it was also hard to talk to [friends], because you don't want to be a jerk. After the movie ['Twilight'] came out, some people said, 'You changed.' And I said, 'I haven't changed, dude," she said. "Your opinion of me has changed because I'm working on this film.' Trust me, my parents would let me know."
