Neighbors were shocked to see the royal couple at Doria's modest bungalow near a McDonald's and a cannabis shop, according to the Sun on Sunday.
One told the British publication, "Meghan is a mommy's girl — their special mother-daughter bond hasn't disappeared just because she's moved to England.
"Meghan will always come back to Doria. This will always be her home.
"They are forever in touch, and Meghan has been here to stay on more than one occasion since going public with Harry," the neighbor noted.
"I even saw him here once, but it's not my place to say any more."
It's believed Meghan, 37, and Harry, 34, stopped off to see Doria, 62, during the return leg of their Australia trip in early November 2018. That wasn't long after the Palace announced they were expecting their first child.
Meghan's mom has stayed out of the spotlight since she attended the royal wedding in May 2018.
But her ex-husband, Meghan's dad Thomas, continues to make waves with his loose cannon comments.
He recently spilled more of their dirty laundry by revealing Meghan had begged him in a letter to stop attacking Harry.
Doria lives quietly in a two-bed bungalow in the Windsor Hills district of L.A.
The Sun reported that her muddy porch is dotted with small plastic signs declaring "trespassers will be prosecuted."
While pregnant Meghan has been a jet setter, enjoying a lavish New York baby shower and a trip to Morocco, Doria stays in L.A., drives a Honda CRV and does all her own chores.
Sources say Doria doesn't want to take money from her Duchess daughter.
A pal told The Sun, "Doria could live in a Hollywood Hills mansion behind huge walls if she wished.
"But she doesn't. She has chosen to stay in the street she's lived on for the past 25 years, where all her friends are and where her community is. She is incredibly popular around here and everyone is fiercely protective over her.
"Meghan said she can move somewhere more fancy, but she has no interest," the source said of Doria, a yoga teacher.
However, Doria is expected to begin staying with the royal couple at the end of March when they move into Frogmore Cottage in Windsor.
After that, it will be baby watch time and Doria no doubt plans to help Meghan and Harry care for her royal grandchild!
