Shields revealed in her new book There Was a Little Girl: The Real Story of Mother and Me, that the tennis star destroyed all his trophies in 1995 after getting upset while watching her flirt with Matt LeBlanc on the set of Friends.
The 49-year-old actress said Agassi stormed off the set after watching her lick the actor's finger in a date scene and verbally abused her telling her she had "made him look a fool" before driving off to Las Vegas in a rage.
"Upon arrival he systematically smashed and destroyed every single trophy he had won, including Wimbledon and the US Open, never mind all the others," she added.
Shields says it took years to replace the broken trophies.
Shields and Agassi married in 1997, two years after the incident, but the Blue Lagoon star wrote she knew she had made a mistake just one day after the ceremony.
"I could not form a sentence. I kept shaking my head as if I had duct tape across my mouth. It hit me all of a sudden -- I knew I had made a mistake. I did not want to be married... I wanted to be a bride but I shouldn't have been married yet."
