Celebrity sibling Solange Knowles, sister of megastar Beyonce, was married Sunday at the Marigny Opera House in New Orleans in an elegant, all-white ceremony. Solange’s groom was Alan Ferguson, 51, a video director.

The theme of the wedding was white. The couple arrived at the former church, now a performance space, on vintage bikes painted white; the wedding party was also dressed in white. The couple lives part-time in New Orleans.

Solange wore an Humberto Leon for Kenzo dress.

Beyonce attended in a white tank dress, and mom Tina Knowles wore a white ruched frock. A frilly white party dress was the look for celebrity niece, Beyonce’s daughter Blue Ivy.

Beyonce and Jay-Z left after the wedding on their private jet. Blue Ivy was tuckered out.
