On the last day of their trip to Barcelona, Mark Zuckerberg and his wife Priscilla were reunited with their close friend Gerard Piqué. The group were celebrating Priscilla's 31st birthday with a private dinner in a restaurant.

Mark naturally took to Facebook to share a candid picture of the festivities, which showed the tech legend sitting alongside his wife and gazing adoringly at her as they shared a laugh.

Seated next to Mark was FC Barcelona football player Gerard, who also posted a photo of the celebrations on Twitter. "Happy to see you again Priscilla and Mark. Hope you have had a great time in Barcelona!" he wrote.

Gerard and his long-term girlfriend Shakira are good friends with Mark and Priscilla. They wrote an open letter on Facebook "from parents to parents" when Mark and Priscilla welcomed their first baby Max last year.

As well as offering their congratulations on the birth of the couple's daughter, Gerard and Shakira, who is a UNICEF Goodwill Ambassador, praised Max and Priscilla for their decision to donate a substantial amount of their Facebook shares to help children all over the world.

"Your commitment to making the world a better place than you found it, and to empowering everyone to help make that a reality through all the tools you've listed here, education for all being one of them, show that success, when shared, has a multiplier effect," wrote mum-of-two Shakira.

"It's not about leaving anyone behind. It's about helping pull everyone, and humanity in general, forward."
