Brown exchanged vows with Etheridge in Honolulu and the couple was joined by their three-year-old son Cassius as well as three of Brown's children from previous relationships, reported Us magazine.
His daughter Bobbi Kristina with late ex-wife Whitney Houston, reportedly chose to stay away from the ceremony, but Etheridge insists the newlyweds had a perfect day.
"We are the happiest couple in the world. It was the most special beautiful day with all our family and friends," she said.
Brown and Etheridge got engaged in 2010 when Brown publicly proposed at a New Edition concert in Jacksonville, Florida.
