Meghan Markle will likely wear a tiara on her wedding day. Will she wear Princess Diana's headdress?

According to royal expert Ingrid Seward, there are chances that the "Suits" star will wear the same tiara as Princess Diana on the upcoming royal wedding. Queen Elizabeth will open her jewelry vault and have Markle pick. Her options will likely include the one that the late Princess of Wales wore on her big day.

"She will have access to jewels from the royal collection made available to her by the Queen," Seward told Us Weekly. "She can choose something suitable, but she might also have the Spencer tiara, which is also Harry's heritage and is the one Diana wore on her wedding day."

"Diana was very proud of her Spencer heritage and I think Harry will like his future bride to carry this tradition on," Seward continued. " She will not own the tiara but will have the choice to wear it if she wants to. If not, she will certainly be loaned a tiara on her wedding day. Harry will present her with a necklace or something from his mother's collection."

Prince Harry and Markle have always wanted to include the royal prince's late mom on their wedding. In fact, this is the reason Prince Harry included a piece of jewelry from his mother's collection in his engagement ring to the "Horrible Bosses" star.

Also, according to some insiders, the couple might consider Princess Diana's favorite designers Catherine Walker and Amanda Wakeley for Markle's wedding gown. "Obviously not being able to meet his mom, it's so important to me to - to know that she's a part of this with us," Prince Harry's fiancée said.

"It is days like - days like today when I really miss having her [Princess Diana] around and miss being able to share the happy news," Prince Harry said during their engagement interview. "But, you know, with the ring and with everything else that's going on, I'm sure she's, she's with us."

In related news, another insider revealed that Prince Harry and Markle will have a wedding cake made from bananas. "This will be the first royal wedding cake made from banana," one source said.
