Well, this is weird: TMZ has a video (NSFW) of celebrity chef Guy Fieri in the middle of an intense fight ... with his hairdresser, Ariel Ramirez. Sources say the two had just landed at San Francisco International Airport and were on their way home in a car service. (Sources say they'd been drinking, not surprisingly.) It's not clear what the fight was about, but it involved Ramirez punching and swearing at Fieri while crying, and Fieri kicking Ramirez. It reportedly ended with Fieri booting Ramirez from the car and Fieri's manager escorting him home in a taxi. "It was just dudes being dudes," says a source. The version from Fieri's rep: "A bunch of guys were messing around. Things got a little out of hand, but they're all good now."
