Rub-a-Dub-Dub -- Lindsay Screwed with Her Tub

TMZ has obtained an incident report from Lindsay Lohan's West Hollywood condo which details some serious damage she did to Harry Morton.

Lohan lives one floor above Harry Morton, son of Las Vegas mogul Peter Morton, who just sold the Hard Rock Hotel and Casino. Lindsay and Harry were once an item. Last month, Lindsay's condo flooded, sending water cascading into her ex's unit and causing extensive damage.

Contrary to published reports, the culprit was not a faulty pipe. According to the incident report, security officers at Sierra Towers went to Lindsay's unit, walked into the master bathroom, "and found the water overflowing in the bathtub." The security officer humbly wrote, "It seems that they left the faucet on. I turned it off."

TMZ sources say Morton's damage exceeded $150,000, and Morton wants Lohan to cough it up.

Lindsay's rep told TMZ Lindsay and her assistant, Jenny, were in New York on the night in question, but TMZ has video of Lindsay at an L.A. club that very night. Lindsay's rep added, "We're very suspicious."
