"Not a great day," Hurley, 45, tweeted Sunday. "For the record, my husband Arun & I separated a few months ago."
The couple married in 2007 at a castle outside of London. They followed up the private civil ceremony with a lavish and traditional Hindi wedding in Jodphur, India.
Hurley, 45, dated actor Hugh Grant for more than a decade and has an eight-year-old son, Damian, from a relationship with film producer Steve Bing.
