PRINCE Harry could pop the question to his girlfriend, actor Meghan Markle, before his birthday in September, according to close friends.

The US soap star and the Prince have a pact never to go longer than a month apart and speak on the phone at least twice a day when they are separated.

Markle apparently feels so comfortable at Harry’s Kensington Palace quarters that she keeps a wardrobe of clothes and a shelf of organic cookbooks in the kitchen.

Meghan Markle — could she soon become a royal?

“Harry has found the girl he wants to spend the rest of his life with,” a friend has told UK media.

“He is fuelling all the talk about the future.”

It comes as Prince William and Harry will open up about their mother, together for the first time, in a new documentary commemorating the 20th anniversary of Diana’s death.

A trailer for Diana, Our Mother: Her Life And Legacy was released yesterday and shows both of the princes leafing through a family album of photographs.

The documentary will explore the relationship between Princess Diana and her two sons.

Speaking in the film, Prince Harry said: “This is the first time that the two of us have ever spoken about her as a mother.”
