The 'Joy' star opened up about her belief in aliens and admitted that when she looks up at the night sky, she imagines spaceships carrying extraterrestrials will descend on Earth and exterminate human life, just like in a Tom Cruise movie.

Recalling the storylines of films such as 'War Of The Worlds', the blonde stunner mused: "Based on history, when we find each other, we kill each other. I don't feel like aliens are going to be like, 'Oh great! Let's get along.' They might not. They might want to destroy us. Have you seen a Tom Cruise movie?

"So sometimes I look up into the stars and I'm like, 'Oh wow... oh god..."

Jennifer was asked to ponder life's important questions on 'The Late Show' with host Stephen Colbert and when asked how she wants to be buried when she dies, she quipped: "Two words. Coffin. Bobsled."

Meanwhile, the 'Hunger Games' star attended the premier of her new movie 'Joy' on Sunday (13.12.15) and unbeknown to her legion of fans, she was vomiting just moments before she stepped onto the red carpet.

A source close to the 25-year-old beauty revealed: "She was ill and vomiting ... but she's feeling much better."
