Liz Hurley Files For Divorce

Elizabeth Hurley has finally filled for divorce from her husband Arun Nayar, four months after announcing they had separated, RadarOnline.com has learned.

The model-turned-actress-turned swimsuit designer filed the paperwork in London Friday citing "unreasonable behavior" on Nayar's part as the cause.

Elizabeth, 45,  who became famous due to her high profile relationship with actor Hugh Grant, married the Indian born textile heir on March 2 2007.

As RadarOnline.com previously reported, on December 12, 2010 she revealed on her Twitter account that she and Nayar had been separated for several months. The admission followed media reports that she had been engaging in a romantic relationship with Australian cricketer Shane Warne.

According to the UK's Daily Mail, Hurley never signed a pre-nuptial agreement and could stand to lose a portion of her estimated $21 million fortune.
