The happy couple.

Alexandra Chong, CEO of dating app Lulu, married her long-time boyfriend Jack Brockway in Jamaica over the weekend.

The wedding was a star-studded affair, with guests including Google co-founder Sergey Brin, entrepreneur Richard Branson, Princess Eugenie and Kate Winslet, according to sources.

Brockway’s brother is Ned Rocknroll, the husband of actress Kate Winslett, who was the star guest at the wedding. An Instagram video shows the actress singing during the ceremony:

The New York Times reports that Chong met her husband at a kitesurfing and networking event on Maui in 2012. A week later, they met on Necker Island, entrepreneur Richard Branson’s luxury island resort.

Branson was photographed at Chong’s wedding and is said to have given a speech. His children Sam and Holly Branson were present at both the pirate raft ride on the river and the ceremony:

Also in attendance at the wedding was Google co-founder Sergey Brin, who mingled with guests during the reception. He was seated next to a woman named Nicole, who we believe is Nicole Shanahan, founder of patent technology company ClearAccessIP. (We contacted her to verify.)

Here’s a shot of the partygoers having fun on the beach:

The evening ended with fireworks over the wedding party. The fact that it is a tech wedding can also be seen from the drone in the corner of the photo:
