Heather Graham finds Las Vegas too superficial

London: Heather Graham believes Las Vegas is it too superficial for her taste.

The 43-year-old actress has returned to the gambling capital of US film the third instalment of `The Hangover`, reported Contactmusic. "I don`t like Las Vegas. People seem phony, they`re spending all their money and it`s sad. And it`s also so cold with permanent air conditioning everywhere. "I`m more the type who wants to be outside and look at a tree. I don`t want to look at a machine," Graham said. Heather is fond of the luxury trailers she and her co-stars Zach Galifianakis, Bradley Cooper and Ed Helms - stayed in during filming. "Well, we had much nicer trailers, they`re gorgeous, you can live in there, and they’re so nice! And Zach has gone on a total health kick, he`s Mr Healthy, he`s observing this really strict diet. He`s this crazy comedian, but now he`s super health-conscious, he doesn`t eat sugar or gluten," she added. Heather does admit to following a similar food ritual. PTI
