The pair renewed their vows in an intimate ceremony in St. Lucia on April 13, according to Us Weekly. The couple -- who have been married for nearly eight years -- rented out the island's entire Sugar Beach Resort for the weekend in honor of the happy occasion.

Around 50 guests, including Damon's BFF Ben Affleck and his wife Jennifer Garner, looked on as the Damons said "I Do" under thatched roofs right at sunset. Reportedly, the groom, 42, wore a tan-colored suit and flip-flops, while the bride, 36, donned a cream-colored gown featuring a sequined belt at the waist.

The couple's daughters -- Isabella, 6, Gia, 4, Stella, 2, and Alexia, Luciana's teenage daughter from a previous relationship -- were in attendance and wore light-colored dresses to match their mom. After the 15-minute ceremony, guests -- who all wore shades of cream and ivory -- were escorted onto the beach for a cocktail reception.

The Damons first tied the knot at City Hall in NYC in Dec. 2005, but have been looking to renew their vows in front of friends and family.
