"No one knew what they said," a source told Us Weekly. "Whatever they said was very emotional. Camila was tearing up."

A-list attendees included Reese Witherspoon, 36, Woody Harrelson, 50, and filmmaker Richard Linklater, 51. After McConaughey and Alves shared a long, passionate kiss, "There was a lot of clapping and everyone was happy," according to an attendee.

John Mellencamp, 60, serenaded the newlyweds with a song based on a Bible verse before the Brazilian feast began. "It was a great night for everybody," a pal told Us.

McConaughey -- who met Alves at an L.A. bar in 2006 --proposed to his Brazilian-born love with a Cathy Waterman engagement ring on December 25, 2011. His new movie, Magic Mike, is in theaters June 29.
