Since Prince Harry and Meghan Markle moved to Southern California, their friendship has changed considerably.

The Duke and Duchess of Sussex do their best to keep their personal and social lives out of prying eyes, but still occasionally learn the identities of some of their famous friends.

Just as we learned this summer that the Duchess joined Beyonce on her Renaissance tour with Kerry Washington and Kelly Rowland, we have learned about two of the celebrities the Duke and Duchess have hung out with over the past year.

Actor Rob McElhenny took to Instagram to share an undated selfie of his "It's Always Sunny in Philadelphia" co-star Glenn Howerton and Prince Harry hanging out at a sports bar and seemingly enjoying life.

"The photo with Prince Harry is iconic," one commented.

Sadly, we may never know how the photo came to be, or whether Harry is great friends with McElhenny and Howerton, or whether they just ran into each other at the bar.

On the other hand, the first photo in the Wrexham Association Football Club co-owner's post shows him having a severe allergic reaction to nuts, with parts of his face extremely swollen and one eye forcibly closed.

"Aside from the mild allergic reaction to nuts, 2023 was one of the best years of my life. 'Thank you to the people and places that made it possible. My life is full of love and joy, and I can't wait for 2024. I won't be anywhere near the Nats."

Mindy Kaling said, "Rob almost made me drop my phone. My son screamed."

As for Prince Harry, we know that he and Meghan are trying their hand at filmmaking in the near future. A crossover between "Sussex" and "Always Sunny" is certainly unexpected, but it's the New Year and anything is possible, right?
