Elizabeth Hurley, who confirmed last year that she was separated from husband Arun Nayar, has formalized the split by filing divorce papers in London. According to Us, the actress, 45, cited her spouse's "unreasonable behavior" as the reason for ending the four-year marriage.

The couple began seeing one another in 2003 and wed in 2007, hosting extravagant weddings in both Britain and Nayar's homeland of India. Nuptials at a castle in the English countryside were followed by a traditional Hindu ceremony in Jodhpur, attended by European royalty and Bollywood stars.

But last year, Hurley, mother of 8-year-old Damian (her son with billionaire Stephen Bing) made some scandalous headlines when she was spotted around London with married Australian cricket pro Shane Warne. The two were accused of an affair, and to set the record straight, Hurley felt compelled to explain on Twitter in December: "For the record, my husband Arun & I separated a few months ago. Our close family & friends were aware of this."
