FIRE IN THE HOLE!

Ellen DeGeneres dove for cover when an explosion rocked the set during a test taping of her upcoming TV talk show! Horrified Ellen felt searing pain in her leg and feared she'd been shot! Pandemonium erupted -- until everyone realized that a lightbulb had fallen from the ceiling and shattered loudly, nicking the star's ankle with glass splinters! After a touch of alcohol (on the wound, of course!) Ellen trouped on.
