Beyonce's sister Solange Knowles tied the knot with boyfriend Alan Ferguson surrounded by friends and family at a church in New Orleans Sunday, E! News reports.

Beyonce, husband Jay-Z and daughter Blue Ivy were among the guests, all of whom wore varying shades of white.

Solange was spotted Friday night hand-in-hand with Ferguson toward the Indywood Theater, followed by Beyonce, where they watched the film "Mahogany", starring Diana Ross.

Ferguson is a video director who has worked with not only Beyonce and Jay-Z, but also Fall Out Boy, Katy Perry, Gym Class Heroes and Nelly Furtado.

The couple have been living in New Orleans for the past few months since moving out of Brooklyn several months ago.
