(Cover) - EN Showbiz - Rosie Huntington-Whiteley believes in "aliens and spirits" but isn't sure about ghosts.

The star is a famous model and has been cast in the latest instalment of the Transformers movie franchise. Transformers: Dark of the Moon revolves around a spaceship which is discovered on the moon and the subject matter has got Rosie thinking about science fiction.

She is adamant there are other life forms in the universe, but isn't so sure about what happens when people die.

"I believe that there's something else out there, but... I don't know what I believe in. That's a good question," she said. "I haven't seen them [ghosts] and I haven't met anybody who I would really trust telling me that they have. I believe in aliens... and spirits, but I'm not sure in what form a ghost would be."

Rosie describes herself as a "risk-taker" which is why she made the move to acting. She was thrilled to hear she'd won the part of Carly, who is Shia LaBeouf's character Sam Witwicky's love interest.

The movie is action packed, which Rosie had no problem with as she isn't easily scared.

"I'd like to think that I'm brave. That's a really wonderful personality trait to have. I would love to think I'm the type of person to go rescue someone," she told Complex magazine. (C) Cover Media
