The Brazilian supermodel tied the knot with Brady in a dusk service at the Monica Catholic Church in Santa Monica yesterday, reports Us Weekly.
According to an unnamed source, the 28-year-old bride walked down the aisle in an ivory and lace strapless gown with a floor-length veil, designed by Dolce & Gabbana.
The insider added that the ceremony had been "very small and intimate". Guests included Brady's one-year-old son John, with ex-girlfriend Bridget Moynahan, and Bundchen's three dogs who were dressed in D&G collars.
Representatives for the couple, who began dating in 2006, have yet to comment on the report.
Last month, Bundchen denied claims that she had become engaged to the American footballer over Christmas, saying: "I don't know how people are so creative...I wasn't even there [with him], how can that be true?"
