Meghan Markle may surpass Princess Diana's popularity.

There is no doubt that the "Suits" star is among the most popular personalities to date, especially with her royal wedding with Prince Harry being only a few months away. Markle's popularity is expected to continue when she officially becomes a member of the royal family. In fact, she could be more popular than the late Princess of Wales.

"The royal family is lucky to have her. She absolutely could be more popular than Diana," Erin Specht, who dated Markle's half-brother Thomas Markle Jr. for about 16 years, told New Idea magazine (via Express).

"Meghan is just a normal, everyday person who's gotten to live a fairytale – not because she chased that or made it, it just came true for her. It couldn’t have happened to a better person," Specht continued.

Specht described Markle as "sweet and kind." She added that Prince Harry's fiancée had a graceful manner.

Specht also revealed that Markle is "desperate to have a family of her own." "She wants kids. She will be an amazing mother. Meghan will get pregnant in her first year of marriage if she can. For certain she will be trying for a baby on their honeymoon – she is going to be a brilliant mum," Specht added.

Many are convinced that Markle could be the next Princess Diana. Just like the late Princess of Wales, the actress is good in connecting with people. In fact, she broke the protocol when she hugged charity co-founder, Alice Thompson.

"My prediction is that Meghan is going to be our new Diana. A wee touch of Meghan adds a bit of sparkle," said Una Mallon, 47, who joined the crowd in Scotland to meet Markle and Prince Harry.

In addition, Markle has been secretly visiting different charities to learn more about the charity sector. Among the place she visited was the Al-Manar Muslim Cultural Heritage Centre.

"Having a member of the royal family that wasn't born into aristocracy, who has the experience of divorce, who has moved countries, makes a difference and makes it easier for survivors to relate to her," said Dawn Foster. "They can feel free speaking with her about race in modern Britain, and their different socio-economic experiences."
