US celebrity magazine Star magazine claimed yesterday that the couple "tied the knot during an intimate wedding ceremony in the couple's adopted city of New Orleans".
But the publication said today: “After further investigation, the sources are not standing by their story.”
A spokesperson for the pair did not comment on erroneous report.
In January, it emerged Angelina and Brad were expecting boy and girl twins
A source had already told rival publication, People: "[There was] no wedding," while Us Weekly concurred: "Bottom line, they aren't even in New Orleans."
Rumours were rife in the last few weeks that the couple had agreed on a £100million pre-nuptial agreement ahead of a wedding set to take place at the city's Saint-Louis Cathedral.
Angelina, 32, has previously talked down the importance of marriage.
She told Vogue in 2006: "We both have been married before, so it's not marriage that's necessarily kept some people together."
Drained: Angelina Jolie, pictured with Shiloh, Zahara and Maddox, is 'constantly tired from taking her four kids to Texas where Brad is filming
We are legally bound to our children, not to each other, and I think that's the most important thing."
The actress is pregnant with twins - reported to be a boy and a girl - and is due to give birth later this year.
The pair already have three adopted children, Maddox, Zahara, Pax-Thien, and a biological daughter, Shiloh.
Angelina was previously married to British actor Jonny Lee Miller and Billy Bob Thornton while Brad split from his wife Jennifer Aniston in 2005.
