Demi Lovato nearly ran over Paul McCartney yesterday.

"I can't believe I almost ran over a Beatle," she tweeted of the exper­i­ence.  "I was pulling into a parking space that some guys were standing in the middle of, and almost hit them… When one of the guys turned around… It was a BEATLE… Yes, YOU HEARD ME… SIR PAUL McCARTNEY!!!"

Despite the near-death exper­i­ence, Macca "was so sweet!!", with Demi adding: "Can't believe I met him today… WOW!"

Wow indeed.
