Heather Mills McCARTNEY only agreed to marry Sir Paul McCartney after he gave up his marijuana habit.

The former beatle had smoked cannabis almost everyday since he enjoyed his first joint with Bob Dylan in the mid-1960s - but Mills McCartney was determined to create a drug-free family environment after their wedding in 2002.

She says, "Him and (his first wife) LINDA smoked it every day for the whole of their lives together. But I would not get married to him if he was taking drugs. I hate it.

"I could not have him lying to our child about not taking drugs and then going for a sneaky puff."
