Usually wedding gifts come in the form of dinnerware or a food processor. When it comes to Ray J’s marriage to Princess Love, sister Brandy gave him the gift of song.

While the couple were doing their wedding dance, Brandy serenaded them with her beautiful rendition of Etta James’s classic "At Last."

Ray J and Princess may’ve been the story of the day, but of that moment, Ms. Norwood stole the show. Brandy’s performance was so good that the newlyweds stopped dancing for a moment to watch her sing her heart out.

As for the actual wedding, Ray J described to People Magazine the moment his then soon-to-be wife walked down the aisle toward him. "Watching Princess walking down the aisle … when I heard the music and I saw her come down, I lost it. I was like, I'm just gonna let it go and enjoy the love and positive emotion. I got real happy as the tears dropped."
