Rumours are running high why Solange Knowles attacked her brother-in-law Jay-Z. Why do you think she lost her cool?
With reps for Jay-Z, Beyonce and Solange yet to comment, the speculation - and memes - continue.
The three are going about their lives like nothing happened. For the most part.
Solange has deleted all Instagram pictures of her sister, except for one, while Beyonce posted a prayer asking for help in navigating relationships that were a bad influence.
But just days after Solange's bust-up with Jay-Z, the singing sisters travelled to Costa Rica together for Kelly Rowland's wedding. Jay and Bey were spotted putting on a united front at a basketball game together on Monday night, while TMZ is reporting that Solange and Jay-Z were spotted jewellery-shopping together in New York.
''Our sources connected with the store say Jay and Solange were in Mr Flawless, where they were looking for women's jewellery for around 20 minutes,'' the site reports.
''We're told the pair showed no signs of strife, and looked at gems with Mr. Flawless himself. They looked, but tried nothing on. They left the store without buying anything.''
The bizarre outburst last week remains a mystery, but that doesn't stop the speculation or plethora of ''sources'' from revealing what ''really happened'' between Solange and Jay-Z.
US magazine reports that Solange had a tantrum after Beyonce and Jay-Z tried to take her home following her alleged spat with designer Rachel Roy.
New York Daily News, on the other hand, says the fight was sparked by a combination of factors. Their ''sources'' say Solange was sullen after Jay-Z snapped at her for allowing her friends to get into the after party by dropping his name. ''Our source said Jay-Z soon got wind of it and snapped at Solange, saying 'don't use my name','' Daily News writes.
What started out as a small tiff then turned ugly in the lift when Jay decided to go to Rihanna's after-party alone.
Daily News reports a ''second source'' as saying Solange ''seemed drunk and irritated ... She said, 'Why can't you go home?' and to Beyonce 'Why does your husband need to go to the club right now?'.''
When Jay-Z allegedly shot back, ''You're one to talk,'' the mother of one apparently became incensed.
Meanwhile, the Mail Online says tension between the siblings-in-law had been simmering for some time because Jay-Z had failed to fulfil a promise to help promote Solange's music career. Their source said: ''Solange's album is coming out soon but there is no buzz about it, which is a bad sign within the industry.
''Solange wants a major career like her sister and she's tired of living in her shadow. She's jealous. Jay-Z promised he would help take her to the next level but he never found the time to keep his word.''
Adding to the motley mix of theories is RadarOnline, which has suggested that beneath the perfect facade of Jay-Z and Beyonce's relationship, lies a history of fighting and infidelity.
They report that Jay-Z publicly lost his cool with Beyonce back in 2013, right before her Super Bowl performance. Perhaps ''screaming fights'' are standard within the family, Radar suggests and Solange simply overreacted.
Understatements aside, Radar is happy to report that despite explosive exchanges not being unusual, Jay and Bey are loved up. ''By all accounts, the couple are happy together despite the drama: As Radar reported, they were even recently spotted dropping $6000 on gold-plated sex toys during a couple's trip to Brooklyn sex shop Babeland,'' the site says.
While the cause may not be clear, the weapon used in the fight is. The Hollywood Reporter has revealed the 'killer' stilettos that Solange was wearing when she kicked Jay-Z. They report Solange was wearing a four-inch pair of Stuart Weitzman Nudist sandals in gold.
You can pick up a pair yourself for just under $600.
