The 61-year-old is going to transplant from Los Angeles to London.
And it is believed that she is really excited to be living closer to her famous daughter.
Doria was reportedly ‘deeply impressed’ by the Royal Family, especially the Queen, during and after her daughter’s wedding, after they made her so welcome.
Her mother has never talked badly about the royal family or her daughter and the pair remain very close.
And it is understood that she quit her job as a social worker for the Didi Hirsch Mental Health Services clinic in Culver City, Los Angeles, in May.
A source revealed: “‘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 also fell in love with England and told me when she got back that it’s somewhere she believes she too could happily live.”
And it looks like the move could happen before her 62nd birthday next month.
