Despite the fact that the two claim to be no longer together, their friends confirm that they are now engaged to wed.
Khan, who has two children from her previous marriage, has reportedly said yes to Grant’s proposal, and plans to walk down the aisle for a second time.
A friend told Britain’s Mail on Sunday, "They started seeing each other again in April. It was on the understanding that they would give it a proper shot and that if they could make it work, they would marry. Hugh has instructed Jemima not to say anything until they make an official announcement. Jemima knows she needs to be 100 per cent certain that this is the right thing for her, which is why they have been so cagey about going public."
