Emma Stone still gets starstruck.

The 'Amazing Spider-Man 2' actress - who has filmed alongside some of the world's biggest stars - admits she still gets excited when she meets her fellow celebrities and their encounters often reduce her to tears.

She said: ''I'm starstruck by most people. I really get starstruck.

I have cried in front of Sheryl Crow, Lorne Michaels and Tom Hanks but he doesn't know it because I turned away really quickly.''

The 25-year-old actress - who starred alongside Bill Murray in 'Zombieland' - said she ''freaked out'' when he arrived on set for the first day of filming, much to the amusement of her co-stars.

Speaking on 'Jimmy Kimmel Live', she said: '' I did not cry in front of Bill Murray but I freaked out in the car when he first came to set on 'Zombieland'.

''I had a meltdown and Woody Harrelson thought it was the most ridiculous thing that ever happened. I just think he thought it was so funny that I was like, 'Ahhh, Bill Murray's coming! Bill Murray's coming!' and then he came and I was like, 'Hey Bill. It's so crazy you're here. It's hot right?'

Emma - who is dating Andrew Garfield - got to know Bill better when the pair worked together on an as-yet untitled project for Cameron Crowe, and lived just three houses apart on location in Hawaii.

She said: ''We've gotten to know each other better ... He was my neighbour for a while, which was just the best. He's just the most generous man.

''I wasn't feeling that well for a little while he was there ... He made me coffee. He got me an umbrella hat because he's really sweet and because I'm fair and he was worried about the sun.''
