The 33- year-old royal has been dating the 'Suits' star for one year, and it has been reported that during that time he often pops to a shop near Kensington Palace to buy his beau her favourite foods to tuck into, which include Reese's Pieces, coconut water and curry sauce, the Daily Star Online has reported.

And it is believed the red head has also purchased a pink fluffy toy from the same site to prove his love for his partner.

Though the couple have been together for 12 months there has been growing speculation surrounding their relationship and taking it to the next step and marrying one another.

And it has been reported Harry has been teaching the 36-year-old actress how to behave like a royal and mentoring her about the demands surrounding a member of the royal family.

British writer, Katie Nicholl, previously said: "He knows how daunting this will be for Meghan and he's keen for her to be relaxed in the company of senior royals."

Meghan has already met with Harry's grandmother Queen Elizabeth II, but prior to their meeting Harry offered Meghan advice on how she should address the British Monarch.

Katie said: "Harry will have made sure Meghan knew how to address the queen and how to behave in her presence.

"He calls her 'Granny,' but after Meghan had curtsied and called her 'Your Majesty,' she would have reverted to 'ma'am.' It seems strange to mere mortals, but it is how [Princess] Kate addresses her."
