The Bellagio hotel in Vegas was on fire Thursday night ... literally.
Flames shot up from the roof of the hotel/casino, which created chaos on the Strip. The main artery was shut down as the Fire Dept. struggled to contain the blaze.
People inside the hotel were evacuated, but no injuries ... at least none that were reported.
The fire became the biggest show in town, as tourists gawked at the scene.
