Engaged since Christmas Day, they married before close friends and family, including their two kids, Levi, who turns 4 next month, and daughter Vida, 2½.

McConaughey, 42, and Alves, 29, a Brazilian model and designer who the actor has told WHO is "the love of my life," kept mum about the wedding – even to some guests – until the last minute.

After the ceremony, wedding guests stayed in dozens of luxury tents McConaughey pitched on his sprawling property for the occasion.
