The Hollywood super couple apparently married in an intimate ceremony on the Turks and Caicos Islands, according to The Telegraph.
The pair have been spending the Christmas and New Year holiday at the private Parrot Cay estate of fashion designer Donna Karan with their six children, Pitt's parents Jane and William, his brother Doug and sister Julie.
News of their reported nuptials comes eight months after Pitt, 49, and Jolie, 37, announced their engagement in April 2012 after seven years together.
Speculation they had finally wed comes after a magazine report in early December claimed the pair had picked up their wedding rings from celebrity jeweller Neil Lane. In November, Pitt told reporters on the red carpet of the New York premiere of his film Killing Me Softly the nuptials would be "soon".
Pitt and Jolie started dating after meeting on the sets of the 2005 romantic comedy action film Mr & Mrs Smith.
