Jay-Z was so disgusted by the controversial verdict in America's Trayvon Martin case, his bubbling anger kept him awake for two days. Neighbourhood watch volunteer George Zimmerman was acquitted of murder and manslaughter charges after fatally shooting the 17 year old black teen in Florida in 2012.
A number of stars have since denounced the jury's decision, while the rapper and his singer wife Beyonce were among those who took to the streets during a demonstration in New York City on Saturday (20Jul13).
The 99 Problems hitmaker has now revealed he didn't sleep for 48 hours after Zimmerman's acquittal, and is shocked by what he sees as America's ongoing racial issues.
He says, "I was angry. I didn't sleep for two days. We all knew there was still a bit of racism in America but for it to be so blatant...
"(The) old guard and their old ideas and their stubborn ways and all that ego and that bulls**t is still there, it still exists. You just hate to believe that."
However, Jay-Z is adamant most young people don't harbour the same hatred as older generations, adding, "This generation right now, they don't see colour in that way. We're a bit removed from those racist feelings because again, it's hard to teach racism when your child is out (at) clubs. It's integrated and the music we listen to is the same."
Daryl Hannah and Kelly Osbourne urged protesters in Los Angeles to remain peaceful as riots broke out in the city on Monday night (15Jul13) over the acquittal of George Zimmerman. A jury found the neighbourhood watch volunteer not guilty of murdering Trayvon Martin in Florida last year (Feb13) after Zimmerman claimed he shot the teenager in self-defence, but Saturday's (13Jul13) verdict sparked outrage across America.
Several demonstrations have already taken place, with Solange Knowles leading a peaceful rally in Brooklyn, New York on Sunday (14Jul13), and on Monday evening, hundreds took to the streets of L.A. to protest against the ruling.
However, 13 people were arrested during the protest, in which a news crew was attacked, according to The Hollywood Reporter. The L.A. Times also reports cops became involved in a stand-off with protesters outside a Walmart store.
Hannah called for calm, writing in a post on her Twitter.com page, "Be peaceful out there - streets shut down in Compton. Justice for Trayvon!"
Osbourne added, "I'm all for the Trayvon Martin protests I just wish they were peaceful protests rather than riots don't let the message get lost to violence!"
Stevie Wonder has vowed never to perform in Florida again until a controversial self-defence law is abolished following the acquittal of the man who gunned down teenager Trayvon Martin. Neighbourhood watch volunteer George Zimmerman was found not guilty of murder and manslaughter charges by a Florida jury on Saturday (13Jul13) after claiming he shot the unarmed 17 year old in self-defence in February, 2012.
Although the state's 'Stand Your Ground' law was not used to sway the jury, it has come under renewed scrutiny as it allows a person to defend themselves with force wherever "they have a legal right to be".
Now Wonder has announced he will boycott Florida and the other 22 other U.S. states which carry similar laws until they are overturned.
Speaking to fans at a show in Quebec City, Canada on Sunday (14Jul13), the singer said, "I decided today that until the Stand Your Ground law is abolished in Florida, I will never perform there again. As a matter of fact, wherever I find that law exists, I will not perform in that state or in that part of the world.
"The truth is that... for those of you who've lost (loved ones) in the battle for justice... we can't bring them back. What we can do is we can let our voices be heard. And we can vote in our various countries throughout the world for change and equality for everybody. That's what I know we can do."
Zimmerman's acquittal has sparked mass protests across America, with a number of stars including Beyonce, her sister Solange Knowles, Rihanna, Chris Brown and Miley Cyrus speaking out against the verdict.
Veteran soul singer Lester Chambers was hospitalised on Saturday (13Jul13) after he was attacked by a woman at the Hayward Russell City Blues festival in California for dedicating a song to Martin.
Solange Knowles staged a rally in Brooklyn, New York on Sunday (14Jul13) to express her outrage after a man accused of murdering tragic Florida teenager Trayvon Martin was acquitted. Neighbourhood watch volunteer George Zimmerman claimed he shot 17-year-old Martin in self-defence in February, 2012, and on Saturday (13Jul13) a jury acquitted him of second-degree murder.
Several famous faces, including Rihanna and Nicki Minaj, took to their Twitter.com pages to complain about the verdict, while Beyonce even held a minute of silence during her Saturday night (13Jul13) concert in Nashville, Tennessee in honour of Martin.
A day later, Beyonce's sister Solange took to the streets of New York City to stage a protest.
The singer attended a rally outside Borough Hall in Brooklyn and held a plaque quoting Malcolm X's famous words: "I'm for truth, no matter who tells it. I'm for justice, no matter who it's for or against."
Hundreds turned out to back Knowles, and she later took to her Twitter.com page to thank them for their efforts.
In a series of posts, she writes, "Thank you to everyone who came out to support Bklyn (Brooklyn) 4 (for) Trayvon rally! This was just a start to a long journey of justice and equality! Seeing & gathering with people today/tonight all for the same fight helped to restore my faith in humanity."
Meanwhile, Jamie Foxx, who led a candle-lit vigil in New York to remember Martin on the one-year anniversary of his death, has taken to his Twitter page to reach out to the teenager's family.
In a post, he writes, "I want to wrap my arms around Trayvon's parents and family during this emotional time. Trayvon will live in our hearts forever. We will make sure that he did not die in vain."
