ST. CLOUD - Kim Kardashian was spotted eating a burger at a St. Cloud restaurant yesterday (Tuesday).

The Hollywood celebrity, and her fiance Kris Humphries, stopped at Five Guys Burgers and Fries.  Humphries owns the restaurant with his parents.

Worker Danielle Moen says they only found-out about the surprise appearance just minutes before they walked in the door.

Moen says Kardashian also took a handful of photos with the customers.

Humphries is a native Minnesotan.  He played for the University of Minnesota Gopher's Men's basketball team for a short time, before turning pro.  He's playing now for the NBA's New Jersey Nets.
