It was a scary day for Ashton Kutcher and Demi Moore -- and everyone else on their flight from Las Vegas to New York yesterday.

The celeb couple's plane needed to make an emergency landing in Las Vegas, after the plane's engine overheated.

"My plane just had to do an emergency landing. Engine over heated. Fire engines everywhere good times," Ashton Twittered, of course. His next post was how he was "happy to be alive" and was looking forward to celebrate life at the Turtle Bay Bar.

Fellow Twitter-lover Demi also posted, writing, "Yep it is always an adventure in Vegas emergency landing and all."

We're glad they're ok -- but this does nothing for my anxiety about having to get on a plane in a few hours. Thanks A & D.
