Los Angeles - Beyoncé Knowles "rescued" her sister's wedding.
Solange tied the knot with videographer Alan Ferguson last Sunday but the nuptials nearly resulted in a disaster when the Losing You hitmaker reacted badly to the seafood.
The bride's mother, Tina, said: "Solange went through the wedding and the sit-down dinner and she was just fine, and then they had a second line in the streets of New Orleans and she was dancing so hard, I think she just got overheated."
The 28-year-old bride disappeared from the festivities for two hours, whilst Beyoncé gave her an allergy tablet.
Tina explained: "Beyoncé took her back to the hotel and gave her Benadryl and in two hours she showed up at the reception and did the dance with her son and just had a ball."
She told Entertainment Tonight: "There wasn't a dry eye in the place."
"The couple were just so heartfelt and I just think the wedding epitomised Solange as a person, and her and Alan's artistic flare."
Solange also took to Instagram to explain the incident and mentioned that nothing could stop her from enjoying her night!
