Elizabeth Hurley has filed for divorce from estranged husband Arun Nayer. The actress -- who announced her split from the Indian textile heir last year after four years of marriage -- filed papers at London's High Court yesterday, citing Arun's "unreasonable behavior."

Hurley -- who has an eight-year-old son, Damian, from a previous relationship -- and Arun split last year, but the news wasn't made public until after it was revealed she had been romancing Australian cricketer Shane Warne. "Painful, sad days. Arun & I separated for private reasons but FTR (for the record) he has been a great father to our son Damian & will always be in his life. (sic)," she wrote on her Twitter at the time.

However, the 45-year-old beauty initially insisted she had no plans to get divorced: "Bored now of silly speculations: no one is divorcing anyone yet, no one is fighting over money and I have no plans to go to Australia. Enough! (sic)." After news of Elizabeth and Shane's romance was made public, the couple split but rekindled in January, and in February she met his parents, Keith and Bridgette, at the sportsman's Melbourne home. The couple initially parted ways in December after it emerged the cricketer had been sending lewd text messages to another woman while he was romancing Elizabeth.
