London, Dec 8 - British actor Hugh Grant has nightmares about turning 50 because he feels time is running out for him to get married and have children.

The Hollywood bachelor, who previously dated actress-and-model Elizabeth Hurley and Jemima Khan, will turn 50 next year, reports femalefirst.co.uk.

"Fifty is not a good number and we all have age terrors sometimes in the middle of the night. I think I might have made a sort of pact with the devil in which I think I can have fun now and sort everything later. But then he comes back and says times up, now you are going to be a lonely man," said Grant.
