Solange Knowles' wedding nightmare

Solange Knowles appears to have suffered a nasty case of hives after walking down the aisle with her video director boyfriend Alan Ferguson on Sunday in a fun-filled New Orleans ceremony, TMZ reported.

The singer was pictured with unfortunate red lumps all over of her face and neck, something which  TMZ has attributed to a food allergy, as she clambered into the back of a waiting car with her sister, Beyonce, and brother-in-law, Jay Z.

Her superstar sibling was at hand to help and appeared to be comforting her, covering her up in the back of the vehicle.

A source told TMZ: 'Solange suffered some kind of food allergy, though she isn't sure what it was from....the hives were gone in a matter of minutes.'
