Michael Fassbender and Alicia Vikander Are Married

Eonline.com: The notoriously private couple tied the knot in Ibiza on Saturday, a source told E! News. While the bride and groom were tightlipped regarding wedding details, the two stars were spotted entertaining friends and family over the weekend after arriving from Paris last week.

On Friday, the group spent the day at the beach, where they had lunch and went on a boat cruise, E! News learned. They had a professional photographer with them who took group shots of everyone.

Fassbender had drinks with friends and also took time to dig for shells with some young family members. At one point, he dove off the back of the boat into the water and went for a swim, an eyewitness said.

Vikander wore a white dress and was twirling around as she took photos and seemed very happy and at ease. She and Fassbender were never too far apart and they got together to give each other a kiss and cuddle from time to time, the eyewitness said.

Later in the day, everyone boarded a sailboat for a sunset party. Champagne was passed around on trays and everyone was doing toasts.

In photos taken Sunday and published by The Daily Mail, the new husband and wife were snapped wearing bands on their left hands as they dined with groups of guests. According to a source, the elated bride and groom hugged their loved ones and looked "so happy" as they enjoyed a post-wedding lunch. Over the summer rumours swirled that the duo had quietly got engaged, but neither confirmed the happy news.

The tight-lipped twosome fell in love on the set of The Light Between Oceans in 2014. The film, based on a 2013 psychological thriller novel by M. L. Stedman, starred Fassbender as Tom Sherbourne, a lighthouse keeper who lives on a remote island in Australia with his wife Isabel, played by Vikander.

Since then, the 40-year-old Irish actor and the 29-year-old Swede have maintained a low-key relationship in the public eye and are rarely spotted together or spoken of each other in interviews.

Fassbender did admit on Good Morning America last year that, "We met on that job and have been seeing each other since."
