Suits stars share their favourite moments from the Royal Wedding

When Suits began seven years ago, its stars probably never imagined one of their own would marry into the British Royal Family.

Yet that's exactly what happened, and when Rachel Zane - sorry, Meghan Markle - wed Prince Harry on May 19, several of her former co-stars made the trip to Windsor to celebrate the occasion.

Two of them, Gabriel Macht and Sarah Rafferty, have now shared their favourite moments from the nuptials in an interview with ET.

"It was surprising to see Elton John play 'I'm Still Standing'," he tells ET, referring to John's performance at the afternoon reception hosted by Queen Elizabeth II.

"He's still standing, he was incredible and that was an incredible moment."

"Just to be a part of such an uplifting story, you know? ... there's so much stuff out there that's so depressing and dark."

Rafferty, known to Suits fans as Donna Paulsen, described attending the wedding as a "wonderful" experience.

"Seeing [Meghan] walk in on her own, in that moment before she met up with Prince Charles to walk the rest of the way, that was amazing," she added.

Their joy at being included in the 600-strong guest list was evident in their social media posts..

Many of the actors shared photos of themselves enjoying their English holiday in the lead up to the wedding.

"I'm beginning to think she might not actually be out getting milk," he captioned a photo of a UK newspaper headline about Markle on the morning of May 19.

The comment was a reference to Adams' tongue-in-cheek reaction to the actress' engagement to Prince Harry last November.

"She said she was just going out to get some milk..." he quipped on Twitter at the time.

Posting a series of photos after the wedding on Instagram, Macht congratulated the royal couple on their big day.

"Enjoyed meeting many of your family and friends and an incredible honour to be a part of the whole celebration," he added.

From all accounts, Markle, 36, had a close relationship with her fellow cast members and received plenty of support from them throughout her relationship with her royal beau.

"And it was like, both of us in the trailer like, 'Oh my. You’re going — you’re dating a prince?'" Hoffman recalled in a recent interview.

I was just like, ‘Well, take it slow. Be careful. Don’t let him hurt you'."

"We worked so many years together on a show. We were with each other for longer than we went to college or high school," she said.

"We became family, in a way."
