One of the first people to know about Meghan Markle and Prince Harry's relationship was her Suits co-star Rick Hoffman. According to Rick, who plays Louis Litt on the USA series, Meghan spilled the news on set as she was getting to know the redheaded royal — and they're still some of her closest pals!

The squad enjoyed a special dinner at a huge table on the evening before the wedding, which they so aptly dubbed "the last supper." Sadly, Meghan was much too busy to attend (getting ready for the even of the decade and all that), but her on-screen husband Patrick Adams was there along with his real wife Troian Bellisario, plus Rick, Gina Torres, Sarah Rafferty and Abigail Spencer. So cute!

Patrick then took to Twitter to share his excitement for his old pal. "Going to bed now and thinking a lot about the strange surreal and wonderful day my friend Meghan is going to have tomorrow," he wrote. "Meghan – wherever you are – we are so grateful to be here to watch you both take this monumental step together. Love deeply and live well." So touching!

Rick also revealed that he gave Meghan some tender advice when she first copped to the new relationship. "I had gotten the news early and I was like, you’ve got to be kidding me," he said on The Today Show. "It was like both of us in the trailer, just kind of like 'you’re dating a prince?’'… and then I was just like take it slow, be careful, don’t let him hurt you." We don't blame Rick for being wary of the royal. Prince Harry doesn't have the best reputation — remember that one time he hooked up with a stripper and played naked billiards during a Las Vegas vacation? Harry also has a pretty extensive list of ex-girlfriends…

Well, we're just glad Meghan didn't take his advice when it came to taking things slow. Just six months after announcing their engagement, Meghan, 36, and Harry, 33, are preparing to walk down the aisle this weekend — and most of the Suits cast will be at the royal wedding to watch her tie the knot. "I hope nothing but, as we all do, the best for her," Gina aka Jessica Pearson, said on the morning talk show. "This is an incredible step in her life and so to bear witness to that is extraordinary."

Her on-screen maid of honor Sarah (Donna Paulsen) added, "We called ourselves the sister wives… we were with each other for longer than we went to college or high school with our friends so we became family, we’re still family so this is a wonderful family affair."

Patrick also recently gushed about Meghan and congratulated Harry for popping the question. "Playing Meghan's television partner for the better part of a decade uniquely qualifies me to say this: Your Royal Highness, you are a lucky man and I know your long life together will be joyful, productive and hilarious," he wrote on Instagram.
