Recording artist Solange Knowles married music video director Alan Ferguson at a church in New Orleans Sunday.
Knowles, 28, and Ferguson, 51, announced their engagement last June after about five years of dating.
All of their 50 or so wedding guests -- including the bride's sister Beyonce, her husband Jay Z and their 2-year-old daughter Blue Ivy -- wore white clothing for the occasion, E! News reported.
Also taking part in the ceremony was Julez, Solange's 10-year-old son from her previous marriage to Daniel Smith.
The Knowles sisters and Jay Z were the subject of unwanted media attention last May when security camera footage showing Solange physically assaulting Jay Z was posted on TMZ and went viral.
"What's important is that my family and I are all good," Solange later told Lucky magazine. "What we had to say collectively was in the statement that we put out, and we all feel at peace with that."
The joint statement to which she refers stated both Solange and Jay Z "assume their share of responsibility for what has occurred" and that the family had "worked through it" and "moved forward as a united family."
