The Estee Lauder model and Grant split up in May 2000 after 13 years together. While Hurley has had a son with ex-boyfriend Steve Bing and is currently dating Indian businessman Arun Nayar, the Notting Hill actor started dating Khan in June 2004.
Hurley remains close friends with Grant and he is godfather to her son DAMIAN CHARLES, three.
She explains, "We're still best friends and Hugh is godfather to my son.
"We don't see a great deal of each other now because we've got completely separate lives and we've moved on with new relationships and families. But I still worship him.
"I do know that he's not getting married either, even though that has been written. I think I would know if he was - and I do know that he isn't."
Hurley also reiterated she isn't marrying Nayar, despite reports to the contrary.
She says, "We're absolutely not getting married. It's a complete and utter myth. We've very happy and I love him enormously."
