Ali's parents, former world heavyweight champion Muhammad Ali and Veronica Porsche Anderson, her sister Hana Ali, and Conway's twin sons Cameron and Kelton, 12, were among the 200 guests at Sunday's wedding, People magazine reported.
The 29-year-old quadruple crown super middleweight champion wore a champagne-colored silk charmeuse strapless gown, the magazine reported.
Kaufman would not release any details of the wedding.
Ali came in third during last season's television competition "Dancing With the Stars."
Conway and Ali met two years ago when he hosted a small party at his home. Conway, 36, proposed last Thanksgiving.
In 2005, Ali divorced her husband and former promoter Yahya McClain.
