As reported by the Mirror, he said: "What, and have Meghan Markle curtsying to Kate Middleton? I don't think so. I don't see that as a runner. They've got their own lives in California."

Royal Highnesses bow and curtsy only to majesties meaning that this is something Meghan would have to do when Kate becomes Queen.

Meghan and Harry have recently created fears that the couple are "drifting apart" - something which has even sparked concerns from their own friends.

Harry, who is still fifth in line to the throne, has travelled solo to various places over the past few weeks - including London, New York and Africa. Meghan is thought to have remained in California with their two children during Harry's solo trips.

However, following speculation that Harry and Meghan are leading "separate lives", a source close to the couple told The Sun: "It is normal for couples to not do everything together."
