In the aftermath of the shocking fight between Solange Knowles and Jay-Z in an elevator on the night of the 2014 Met Gala on May 5, Beyonce is putting her gorgeous foot down.

Star magazine reports that this month's brouhaha was not the first time that Solange has lashed out violently. "[Solange] apologizes and says it won’t happen again, but it does," according to a source.

Now, the Queen Bey, 32, is reportedly making it clear to her sis in no uncertain terms that she'll take her husband's side if Solange, 27, attacks him again. "Beyonce made it clear that Solange is never to get violent with Jay again," says the insider. "Jay is her husband and first priority. She doesn’t want to have to choose between them, but if it came down to it, she would."

Yikes. We can't say we blame Beyonce for getting frustrated by Solange's hostility toward her husband, as Solange definitely seemed to be the aggressor in the elevator fight. Rumors have emerged that designer Rachel Roy's flirtiness with Jay may have been what set Solange off. 

Are you surprised that Bey apparently would side with her husband in the future?
