British tabloid The News of the World reported Hurley, who wed Indian textile tycoon Arun Nayar in 2007, spent two nights with the former Aussie leg-spinner in his London hotel suite this week.
Australian paper Herald Sun on Sunday claimed that the secret lovers were captured on video in a series of sizzling public encounters.
"They were so passionate they looked like honeymooners. It was electric," an on-looker outside the hotel told the paper.
With eyes closed and arms wrapped around each other, the unlikely couple were reportedly spotted exchanging kisses after coming out of Warne's luxury 1,750 pound-a-night suite -- less than one mile from Hurley's London home.
The paper also added that on their second night together, they were locked away in the same suite for more than 11 hours.
The pair were also said to have enjoyed a night out together with Hurley's close friend and Hollywood actor Hugh Grant [ Images ], while there was no sign of actress' husband Arun Nayar, or her eight-year-old son Damian, according to the tabloid.
Three years ago, 45-year-old Hurley married Indian origin multi-millionaire textile heir Arun in a series of lavish high-profile ceremonies.
It was also claimed that Hurley has been flirting with Australian sporting giant Warne, 41, for months via Twitter. And on Wednesday, he flew into the UK to shoot interviews for his new TV show Warnie, which is about to launch down under.
He was driven from London's Heathrow to the Royal Garden Hotel in Knightsbridge -- a popular choice for touring cricket teams. But within minutes, Warne, now divorced, was driven to the nearby Bentley Hotel in South Kensington, a place popular with celebrities and visiting dignitaries.
The cricketer checked in and disappeared into a suite, it was reported.
Hurley had spent the morning on a photo-shoot and later emerged from her 5 million pound home in Chelsea [ Images ] in a white coat, clutching designer bags, and drove to the Bentley, just five minutes away, in her new 70,000 pound black Range Rover [ Images ].
She parked in a residents' bay on a side street by the hotel and her face lit up when she spotted Warne -- waiting for her outside the front entrance.
The couple reportedly hugged and kissed each other, locked in an embrace for a full 10 seconds."It was way, way beyond the sort of welcome you might give a friend," another witness said.
