Hilaria, 33, looked breathtaking in a sparkling white gown with delicate sheer details. Their adorable kiddos, Carmen, 3, Rafael, 2, and Leonardo, 9 months, all wore white and blue as members of the wedding party. Baldwin's daughter, Ireland, 21, was also a part of the special day and donned a summery, striped dress. Alec wore a classic suit to the outdoor ceremony.
The event was reportedly held at the Wolffer Estate Winery in Long Island, New York.
The 59-year-old actor revealed that he was getting married again earlier in the week at the premiere of "Blind," where he told E! News, "I see what I have and I'm very lucky. We're getting remarried on Friday."
Congrats to the whole family!

#tbt this is one of my fav pictures of me and Michelle from my wedding(WHICH WAS 10 YEARS AGO TOMORROW!) I love how far away and tiny she looks in the mirror even though she was basically standing right next to me. Thanks to @amyandstuart who are the actual greatest wedding photographers around.

We set up our Leica on the tripod and took this photo upon returning from the Philipsburg courthouse, marriage license in hand. I adore this photo for many reasons... that I had just married the love of my life, that we were in Montana, & that we had our baby girl Sissy with us. #nationaldogday #love
