We knew Solange Knowles and Alan Ferguson have been together forever (and that he's WAY older then her), but we always forget that they're not married. Well, until this weekend, anyway!

Knowles, 28, and Ferguson, 51, are set to tie the knot in New Orleans on Sunday, according to Us Weekly. On Friday the wedding party will have a movie night, and the rehearsal dinner is set for Saturday. Beyonce and Jay Z have to be on the guest list, right?! Guess we'll find out...

The duo reportedly got engaged on June 23 while on vacation in Jamaica, and they've been together for about five years. Solange was previously married to Daniel Smith from 2004 to 2007, with whom she has a 10-year-old son, Julez.

Congrats!
