Matt Damon and wife Luciana Barroso said "I do" for a second time with close friends at hand in the Caribbean island of St. Lucia.

Stars attending the happy gathering included his best friend Ben Affleck with his wife Jennifer Garner.

"This isn't a 'Hollywood' wedding," said an insider to Us Magazine. "Matt wanted it to be fun, happy and private. He felt like Luciana deserves this, first and foremost."

Another source told US: "This is the perfect place for this wedding. You can [go] here for serenity."

The couple's daughters Isabella (6), Gia, (4), Stella, (2) were all there along with Alexia, Luciana's daughter from a previous marriage.

Damon originally wed Luciana in a private civil ceremony back in December 2005 at City Hall in New York City.
