Singer left in car with her sister after fight; leaving rapper to travel home alone 

Jay Z was viciously attacked by his wife Beyonce's sister Solange as the trio left the Met Gala after party in New York last Monday.

The 27-year-old was caught on surveillance camera lashing out wildly at her brother-in-law, 44, with both her arms and her legs, while her sister stood beside them looking curiously impassive. 

The famous family were in an elevator descending from a soiree that followed the annual fashion fest at the Metropolitan Museum of Art.

The seemingly unprovoked attack plays out in footage obtained by TMZ.

Solange can clearly be seen kicking and swinging violently at Jay Z, the father of her two-year-old niece, Blue Ivy, after the trio step into the elevator.

According to TMZ sources, Solange was screaming at her family member when the fight erupted.

In the footage, a man who looks to be a bodyguard tries to hold Solange back but she manages to reign blows on the rapper several times.

No remorse? Whatever Solange's problem with her brother-in-law was, it was still smouldering as she stormed off into the night followed by her sister

During the frenzied altercation, Jay Z grabs her stiletto clad foot to block a kick but never attempts to retaliate.

Beyonce seems sanguine throughout, and appears to be trying to calm her sister down.. . at one point she removes the long train of her dress from the fray.

The bodyguard can also be seen pushing the emergency stop button in the elevator at the 12th floor, no doubt stop the fight spilling out in front of photographers.

The face says it all: Bey tries to keep calm as her husband staggers behind

Jay Z's shocked appearance and hand to face as Solange marches angrily ahead after leaving the elevator were captured on film, however.

Beyonce tried to muster a showbiz smile as the threesome left but then tellingly departed with her sister in a car while her husband left separately.

It's not yet known what provoked the fight, however, the famous couple looked as happy as ever as they attended a Brooklyn Nets game on Saturday while Solange played a gig in New York.

Solange and the music mogul have been close for over a decade, with Jay Z - real name Shawn Carter - taking a big brother style role to the fledgling star after he started dating her sister.

Beyonce and Jay Z were famously friends first but started a relationship way back in 2001, they then married in 2008.

Mrs Carter is extremely close to her younger sibling, and made a surprise appearance at Coachella this year to support Solange's set at the California music festival.

Solange regulaly accompanies the couple to events like the Met Gala and the Grammy Awards.

Always in Beyonce's shadow despite her own immense talent, Solange had a few stints in Destiny's Child, before signing with her father's Mathew's Music World Entertainment label; he and he girls' mother Tina had quit their jobs to focus on their eldest child's career.

But it paid off for Solange initially, too, as her her first studio album Solo Star - released when she was just 16 in 2003 - was a quiet success.

Just a year later, however, she married Daniel Smith, and after giving birth to their son Daniel Julez J. Smith Jr, moved to Idaho, where she occupied herself with writing music for her sister and ex Destiny's Child stars Kelly Rowland and Michelle Williams.

But she missed the buzz of performing herself and after divorcing Smith in 2007, Solange threw herself back into the fray moving to Los Angeles so she could begin to start recording her own material.

It paid off as her second album, Sol-Angel and the Hadley St. Dreams, hit No. 9 on the Billboard 200 and garnered positive reviews.

She set up her own label, Saint Records, and recorded the album, True, in 2012 and has plans for a follow up later this year.

While no Beyonce, Solange is recognised as fashion icon and her Motown songwriting roots are respected throughout the industry.

Before the divorce: Beyonce and Solange with parents Mathew and Tina in happier times

The family was rocked when the girls' mother Tina filed for divorce from Mathew, who was then still Beyonce's manager, after it emerged he'd fathered a child during an extra-marital affair with Alexsandra Wright.
The Crazy in Love singer singer later ended her business relationship with her father, and neither sister attended his wedding to Gena Avery last year.
As a family unit, they've still remained strong it had seemed, with Solange mentioning frequently in interviews that her son and baby Blue are more like siblings than cousins.
