Jessica Biel 'open-minded about aliens'

Jessica Biel has admitted that she believes that aliens could exist.

Showbiz Spy claims that the actress, who voices a character in alien film Planet 51, believes that people should be open-minded about the possibility of extraterrestrial life.

"I definitely believe in the possibility of intelligent life on other planets," she said. "There's just so much space out there not to believe in that."

She continued: "For me, the idea with this movie is to be open to change. You should be accepting of change because only through change can you grow and learn more about yourself, as a human or alien."

Planet 51 is due for release on December 4.
