In a picture obtained by Inside Edition, Doria is seen in a white, loose t-shirt, comfortable pants and sneakers. She was also carrying three bags - leading many to speculate Meghan's mother has a long stay ahead of her.
A close friend of Meghan's told Express: 'She is getting ready to move to London. I think she will be going as soon as possible.
'I know that she was eager to live closer to her daughter.'
'She hasn’t been staying at her house for a while now.
'She has only visited the house very occasionally and when she is there she has had a security guard with her. He has been with her since about November.
'She is fiercely loyal to Meghan and would never betray her like the rest of them. They are so close.
'She also fell in love with England and told me when she got back that it’s somewhere she believes she too could happily live.'
Earlier this month the National Enquirer claimed that the 37-year-old Duchess of Sussex had been secretly visiting fertility doctors following her May 19 wedding, at that Doria had been with her every step of the way.
'Harry and Meghan want to get pregnant as quickly as possible after their wedding,' a friend tells.
'They both know that as Meghan gets older, it can get increasingly harder to conceive - and they are both keenly aware of her vulnerability to health complications and the chance of miscarriage the older she gets.'
Along with fertility check-ups, Meghan also visited London-based nutritionist Melanie Brown at Kensington Palace, insiders told the Enquirer.
Brown, a 'specialist in fertility, IVF, and pregnancy,' who works out of Duke Street, gave Meghan pointers on 'pre-conceptual and pregnancy nutrition, including weight loss and gain, and immune issues.'
Harry, 33, also reportedly 'stepped up', meeting with nutritionist Gabriela Peacock on how he can drop weight and boost fertility.
