Oscar De La Hoya is being sued a famous ex-Golden Boy Promotions employee -- who claims the boxing star would call him at all hours of the night to save him from situations when he was "highly intoxicated."
The man behind the suit is David Gonzalez -- a famous L.A. radio star known as "Tattoo."
FYI -- Tattoo first appeared on Power 106 back in 2001 and agreed to have the words, "I slept with Shaq" tattooed on his forehead in exchange for Lakers playoff tickets. He later got the tattoo removed.
