Last week, News of the World published pictures and a video of the 45-year-old actress kissing Warne.

Hurley and Indian textile heir Nayar began dating in 2003 and wed in March 2007 in two lavish ceremonies — one in a palace in Jodhpur, India, the other in a castle in England. She has an 8-year-old son, Damian, with millionaire ex Stephen Bing. Hurley also dated Hugh Grant for 13 years before calling it quits in 2000.
