Renowned lawyer Robert Shapiro - most famous for representing O.J. Simpson in his murder trial - was rushed to a Los Angeles hospital on Tuesday for emergency surgery, DailyMail.com can disclose.

Shapiro, 76, was due in court in Santa Monica for his client, billionaire developer Mohamed Hadid's controversial monster mansion civil case.

But one of Hadid's other attorneys, Bruce Rudman, told Judge Craig Karlan that Shapiro had been rushed to hospital Tuesday morning.

'I believe it's some kind of stomach surgery,' he told the judge.

Shapiro appeared to be in good health as recently as Sunday, attending Elton John's annual AIDS Foundation Academy Awards Viewing Party with his wife Linell.

Shapiro represented O.J. Simpson when the football star was accused of murdering his wife Nicole Brown and her friend Ron Goldman in LA in June 1994.

Simpson was acquitted after a sensational trial in which Shapiro featured prominently.

Other notable clients of Shapiro include Darryl Strawberry, José Canseco, Vince Coleman, Steve Wynn and Wynn Resorts, actress Eva Longoria and Rob Kardashian - whose father Robert Kardashian worked with Shapiro on the Simpson case.

Shapiro is currently representing billionaire Hadid over his plans to partly demolish his controversial 'mega mansion' in Bel Air, which are still up in the air.

Hadid - the 70-year-old father of supermodels Gigi and Bella Hadid - is being sued by angry neighbors of the 30,000-plus house in ritzy Bel Air.

The disgruntled neighbors - who have dubbed his mansion 'a gigantic monstrosity' and 'Starship Enterprise - brought their lawsuit to try to force Hadid to tear down the property which they say is not only an eyesore, but also poses a threat to their homes.

To support their suit, the neighbors commissioned photographs - taken by drone and featured exclusively in DailyMail.com - which illustrate just how colossal Hadid's house is.

Hadid - 70-year-old father of supermodels Gigi and Bella Hadid - is being sued by angry neighbors of the 30,000-plus house in ritzy Bel Air. He was ordered to demolish the illegal third floor of his unfinished Bel-Air mega-mansion on February 1

In an exclusive interview with DailyMail.com earlier last month, Hadid vowed to 'finish, not demolish' the partially-built mega-mansion despite being ordered to tear down the third story of the property.

Hadid told DailyMail.com that he had applied to LA city planners for new permits that would allow him to downsize and complete the house so that it complies with building regulations.

'Once we get those permits, I want to finish the house,' he added. 'I plan to demolish part of the third story of the house. We will demolish what we need to and make it safe for the neighbors - but I will finish the house.'

The saga of how Hadid set out to build one of the biggest and most expensive luxury homes in LA has been full of controversy since he bought the hilltop plot in 2011 for $1.9 million. He knocked down the ranch-style house that was already there and started building his monster mansion.

Neighbors watched with increasing alarm as the massive house grew bigger and bigger, adding a 70-seat movie theater, plus two huge decks included on the property, which are also illegal, they insist.

But Hadid - hoping to sell the giant mansion for $100 million plus - continued to build, despite orders from Los Angeles City to stop, and in December 2015, in an almost-unprecedented move, the city decided to prosecute him criminally.
