Jay Z and Justin Timberlake rocked a sold-out show at Yankee Stadium in the Bronx on Friday night, just a day before the rapper and his wife attended a rally in memory of slain Florida teenager Trayvon Martin.
But the 17-year-old was already on Jay Z's mind at the show, who dedicated "Forever Young" to Martin.
"This is for Trayvon, so light up your cell phones New York!," Jay Z told the audience, while Timberlake added, "One more time for Trayvon New York!"
Both Jay Z and his wife, Beyonce, have been openly critical of the jurors' decision to acquit George Zimmerman of Martin's murder.
Beyonce posted an all-black Instagram photo the night before Zimmerman's sentencing, writing "#justice4trayvon."
When the verdict was handed down shortly before the 31-year-old performer's July 13 concert, she asked for a moment of silence in Martin's honor.
