They’re still in the honeymoon phase, so it’s not surprising that during their appearance 
at the Royal Foundation Forum late last month, Prince Harry and Meghan Markle couldn’t keep their hands off each other. But while their affectionate behavior may be adorable to many, one person isn’t so thrilled: Harry’s grandmother! Sources tell Woman’s Day that Queen Elizabeth has warned Harry to tone down the PDA with his bride-to-be

She also advised him to start acting more prim and proper like the other royals — like Prince William and his wife, Kate Middleton. An insider reveals, “Being affectionate just comes naturally to Harry and Meghan, but it’s totally against royal protocol. The Queen isn’t thrilled about it at all, and word is she summoned Harry to the palace to remind him what’s expected of a royal. All the hand-holding just isn’t the royal way at all.”

Harry, 33, will marry the 36-year-old former Suits actress at St George’s Chapel at Windsor Castle on May 19, and to prepare her for royal life, she’s having etiquette and elocution lessons in the run-up to the big day. “Meghan is such a warm person, but being a royal is very different to being a celebrity, and Meghan still has a lot to learn,” says the insider.

But the down-to-earth star’s tactile nature is a breath of fresh air for Harry — and he doesn’t want her to change. The LA native has become a hit with the British public, and has been compared to Harry’s late mother, Princess Diana. Our source adds, “Harry really loves that Meghan is so kind and open to everyone she meets, regardless of their status, and he doesn’t want her 
to lose who she is when they get married.”

Still, Harry knows he and Meghan will have to tone things down a little from now on. “Harry has so much respect 
for his grandmother,” says the insider. “And while he doesn’t 
see anything wrong with what they’re doing in public, he certainly wouldn’t want to be seen as disobeying her orders.”
