Kelly Clarkson: Disneyland Trek Before Baby Drop

Kelly Clarkson was a trooper Wednesday, braving the crowds and the 80 degree heat as she trudged through Disneyland ... 9 months pregnant!

Kelly hit all the hots spots ... Small World, Autopia, Tomorrowland, the works. She had a VIP handler but no entourage.

Kelly's due any day. What we don't know ... whether she's walking a lot to induce labor.

Assuming all the walking didn't do the trick, she's supposed to appear as a guest judge and performer Thursday night on "American Idol."
