Gordon Ramsay took a nasty tumble Saturday night after he completed a practice lap at the Las Vegas Grand Prix. Ramsay was enjoying his first outing since welcoming his sixth child after his wife Tana gave birth to a son Jesse James. Gordon was spotted catching up alongside the likes of Rod Stewart - before he and DJ Steve Aoki raced each other in a lap before the actual competition kicked off. But Gordon got dizzy as climbed out of the car and fell to the ground. He had to steady himself for a few moments, while still in his helmet from the race. Luckily he was soon back on his feet, giving Aoki a hug.
