Ashley Greene thinks working on the 'Twilight Saga' feels like school.

The actress - who plays vampire Alice Cullen in the hit movie franchise - admitted that because the young cast have been working together for so long, it was similar to going through the education system as a group.

She explained: "We all came into this as naïve kids and we weren't quite sure where it was going to go. So to come back to 'New Moon', we were all completely different. 'Eclipse' was the same. We were all growing with these films.

"When we're done with the fourth one it's going to be an emotional moment for sure. It's like graduating high school."

The 23-year-old star also admitted she "laughs" at the stories which are constantly made up about her.

She added to Total Film magazine: "The attention got more severe from the second to the third film. I think the biggest thing I've learned from that is that the media will go to the depths of the earth to get a picture because that sells magazines. People just believe what's on the internet or in magazines- when you're first-hand experiencing it, you know that some of this stuff is so untrue. You just have to laugh about it."
