Alice Eve believes in aliens.

The 31-year-old actress says her 'Star Trek Into Darkness' director Jj Abrams was once told by an astronaut that he had come across extra terrestrials in space and JJ revealed all during a Skype chat with other astronauts aboard the International Space Station.

She told chat show host Jimmy Kimmel: ''JJ said he sat next to an astronaut once who had told him that he had seen 'forms or shapes' that make him believe in alien life which you know is really scary. And exciting.

''And so the response the NASA base gave us when JJ asked this question, 'Have you seen alien life?' was so rehearsed and so clear that they have seen [aliens].''

Alice previously revealed she feels ''incredibly lucky'' to have landed a part in the 'Star Trek' sequel.

She said: ''I feel incredibly lucky. I would say it's a once-in-a-lifetime opportunity. It's not once-in-a-lifetime, but it is rare.

''It's one of life's great pleasures to enjoy the group you work with, because we all know what it's like when you don't.''
