We had no doubt that things were getting serious between Prince Harry and Meghan Markle for so many reasons — the first swoon-worthy pics of the two together and their epically romantic getaway, not to mention a sleathy-yet-public declaration of love — which is why those close to the pair are expecting an engagement SOON. And now it looks like Harry is upping the ante yet again by introducing his love to Duchess Kate and Princess Charlotte. The deets? So adorable!

It seems like the duo are making the rounds with the relatives, as it’s already been reported that the young prince has met Meghan’s father and she, in turn, has met Prince William and Prince Charles while also receiving approval from Harry’s grandma, the Queen herself.

But when Kate’s turn came around, the duchess made a special effort to meet Harry’s love. Celebrating her 35th birthday on Monday, Kate left her home in Norfolk immediately afterwards to head to London for the intro on Tuesday. Prince George apparently stayed behind for school, but little Charlotte accompanied her mom to Kensington Palace, where they met Meghan in their private apartment.

Meghan was ready to make a good first impression by gifting Kate with a leather-bound “dream diary” for her birthday, and the two apparently hit it off while Meghan also spent time with Princess Charlotte, who obviously charmed the Suits actress with her adorable ways.

Sounds like things are going royally well. Will Kate and Meghan be new besties as well as sisters-in-law? We can totally see it happening.
