LOS ANGELES – Tensions between Solange Knowles, her sister Beyonce, and her sister’s husband Jay Z are nothing new.
According to sources close to the family, the surveillance video of Solange allegedly going after Jay Z in a New York City elevator comes as “no great surprise,” as tempers among the three have flared numerous times over the years, mainly over minor disagreements.
We’re told Jay Z is fiercely protective of his wife, which may have contributed to Knowles’ apparent outburst, which is said to have been sparked by a simple misunderstanding.
An insider told FOX411 that Solange also got mad after another misunderstanding involving Jay-Z and Beyonce years ago, when she insisted before a local TV interview that no Beyonce questions be asked. The source said Solange then “flipped out” after seeing a tease piece on the station about Jay Z, before being assured by producers that her interview was not live, and the piece was not related to her segment.
Solange has also dropped little digs in the press here and there over the years.
“It would be so much easier for me to put on a little black dress, straighten my hair, and sing about dancing in the club, but it’s not my job to prove anything,” Solange said during a 2010 interview with fashion site Refinery29. “I’m here to make music, to inspire myself. I’m not selling my likeability, I’m sharing my journeys. If you don’t like it, believe it’s real, or understand it… then keep my name out of your mouth.”
In 2012, the R&B singer also told the New York Times that she would not record with her A-list sister.
A couple of days before the alleged elevator incident, Beyonce posted a message on Instagram: “Lord, l lift up every one of my relationships to you and ask You to bless them… Help me to choose friends wisely so I won’t be led astray… Give me discernment and strength to separate myself from anyone who is not a good influence. I release my relationships to you and pray that your will be done with each and every one of them.”
RadarOnline.com reports that Solange has since deleted all pictures on Instagram of her with her famous sibling, with the exception of one vintage photograph posted last year.
However, family relations aren't always strained. Just a few weeks before the alleged kerfuffle, the Knowles sisters and Jay Z attended California’s Coachella Music Festival together, and Solange even brought her sister to the stage for a surprise dance show.
Reps for Beyonce, Solange and Jay Z did not return our requests for comment.
