An expert has shed light on why Meghan Markle has decided to change her surname after she recently shared that she and her children now go by a different one.

Meghan, 43, who has two children—Archie, five, and Lilibet, three—with Prince Harry, gave a rare glimpse into her family life in her new Netflix lifestyle series, With Love, Meghan, which premiered this week.

In the second episode, she revealed that she now uses a new surname.

While chatting with her friend Mindy Kaling about their favorite takeout meals, Meghan reminisced about eating a lot of fast food growing up.

“I don’t think anyone in the world knows that Meghan Markle has eaten Jack In The Box and loves it,” Mindy said.

But Meghan quickly shifted the conversation, commenting on how unusual it felt to hear her full name.

“It’s so funny you keep saying Meghan Markle, you know I’m Sussex now.

“You have kids and you go, ‘No, I share my name with my children.’

“I didn’t know how meaningful it would be to me, but it just means so much to go, ‘This is OUR family name. Our little family name.’”
