The happy couple were all smiles with their three children — daughter Carmen, 3, and sons Rafael, 2, and Leonardo, 9 months — and the actor’s 21-year-old daughter Ireland.
The pair shared several snapshots from the renewal ceremony on their Instagram pages.
The couple were first wed in June 2012 in front of family and friends at the Basilica of St. Patrick’s Old Cathedral in Manhattan.
Alec welcomed Ireland with his ex-wife, actress Kim Basinger.
