Socialite JEMIMA KHAN is turning her hand to script writing in the wake of her split from actor Hugh Grant. The couple announced their break-up in February (07), after nearly three years together, and Khan is keen to take her mind off the failed relationship with an untitled play about a billionairess. She'll be getting help from writer/film producer Gillian Slovo, who has written various crime novels. Ex partner Grant will also be tapping at the typewriter this year (07) - he's writing a novel.
