Kate Middleton and Prince William were reminded of their royal wedding on their last night in Boston.
Ellie Goulding, who performed at the couple's 2011 wedding reception, was also a performer at William's Earthshot Prize Awards ceremony on Friday.
After the show, the royal couple, both 40, chatted with performers backstage. They were pictured excitedly catching up with Goulding, who was the voice behind their first dance as husband and wife.
The British songstress, 35, who is also close friends with William's cousin Princess Eugenie, previously opened up about singing at the royals' reception. Goulding serenaded the newlyweds with her version of "Your Song," originally written by Sir Elton John, a close friend of the late Princess Diana.
"I mean, talking about scary… I was so nervous that my hands were shaking," Goulding told Australian Vogue in 2016. "That was one of my memories, I remember looking down and just seeing this. Chris, my pianist, I looked over at him and he looks at me like, 'Literally, you have just s— yourself. I know it in your face that you've just literally pooed yourself.' "
Goulding also added that she wasn't so sure that she was the headlining performance.
"I thought I was a decoy," she said. "I thought I was a decoy for someone else. It could happen! At the time, [Lady] Gaga was everywhere, and rightly so, she was killing it, and you know, Beyoncé and Jay Z, and then, you know, me."
Goulding was one of several performers at Friday's ceremony. Billie Eilish, Annie Lennox and R&B duo Chloe x Halle also entertained the crowd.
After the show, William and Kate met the presenters and performers ibackstage before attending a private reception thanking those who have helped to deliver the event in Boston.
