Hugh Grant's ex Jemima Khan is not dating Australian cricketer SHANE WARNE, the heiress' mother has claimed. The British socialite, 33, was reported to be romantically involved with the 38-year-old sporting ace, after they were snapped together on several occasions in recent months. But Khan's mother, Lady Annabel Goldsmith, has dismissed the reports. She says, "It's such nonsense. He's (Warne) an old family friend. We've all known him for years through charity events. He's a great friend (of the family)."
