The pair's relationship hit headlines in Britain on Sunday (12Dec10) when the News of the World reported the actress had spent two nights at a London hotel with cricket ace Shane Warne last week (begs06Dec10).
Hurley subsequently told fans on Twitter.com, "Not a great day. For the record, my husband Arun & I separated a few months ago. Our close family & friends were aware of this."
However, her claims were thrown into doubt after her own mother, Angela, told a U.K. tabloid she "didn't know" her daughter's marriage to the Indian tycoon was over.
And now, further questions have been raised after Nayar's millionaire father Vinod insisted he was also unaware of the pair's split.
He tells Britain's Daily Mirror, "We had no idea Arun's marriage was on the rocks. I'm hoping that now Arun will get back home.
"I have messaged him. I am shocked."
