Among her guests was pal Cressida Bonas, who also once dated Harry.
Goulding and Jopling's guest list also included A listers and royalty: Katy Perry with her boyfriend Orlando Bloom, actress Sienna Miller, James Blunt and Princess Beatrice with her love Edoardo Mapelli Mozzi.
Goulding had a rumored fling with Harry in 2016, just before he hooked up with Markle.
That year, they were spotted kissing at the Audi Polo Challenge.
Royal watchers know that Bonas, once touted as a possible Harry bride, just got engaged to Harry Wentworth-Stanley.
She was Harry's steady from 2012-2014.
But the Prince married Suits actress Markle (with Bonas attending their royal ceremony) and now Goulding has wed Jopling, an art dealer who has worked for Sotheby's in New York.
The singer went sweet and old-fashioned instead of sexy for her wedding dress choice, stunning the crowd with a long-sleeved, high neck look.
Meanwhile, Perry and Bloom appeared cozy and possibly got some ideas for their own rumored wedding.

Goulding and her man were thrilled to celebrate their wedding with some big name guests! Before the nuptials, Goulding wore a cathedral length veil over her face.
The two said their "I dos" at York Minster Cathedral.
The "Lights" singer looked closer to a Victorian bride than a modern one. She decided not to show a lot of skin in her wedding dress, which boasted a train.
Will They Wed?
Pop superstar Perry arrived at Ellie and Casper's wedding in a water-colored style print dress by Olivia Rubin and a pale blue collarless coat. Her boyfriend Bloom sported a morning suit.
So In Love
Perry and Bloom looked closer than ever at the very British wedding. A source recently told Radar that they are disagreeing about their own nuptial ideas, with the singer wanting a more lavish ceremony than her actor beau.
Harry's ex Bonas is now engaged to fiancé Wentworth-Stanley. She flaunted her huge ruby and diamond engagement ring at Goulding's wedding and looked cute in a flowing white dress decorated with red flowers and a matching red headband.
Bonas spent a couple of years with Harry but sources said she was too overwhelmed by the attention she was getting with the royal and they broke up. Former actress Markle is comfortable in the spotlight.
Princess Beatrice is a friend of Goulding's and brought her controversial man Mozzi to the ceremony. The royal looked sharp in an emerald green dress by The Vampire's Wife and a black leather floral headband from Yorkshire milliner Justine Bradley Hill.
Goulding, who released an album called Halcyon, wore a bespoke Chloé wedding dress designed by Natacha Ramsay-Lévi. She's been a bikini babe while on holiday with Jopling, but turned modest to marry him.
Rusty Wedding Ride
In a playful touch, the bride was seen climbing out of a blue VW camper van on her way to the cathedral.
