LL Cool J won't perform in the Wawa Welcome America Fourth of July Concert on Benjamin Franklin Parkway on Friday, saying he won't "cross a picket line" amid the ongoing strike in Philadelphia involving the city's largest municipal workers' union.

In this life we are only measured by how we uphold our morals and standards, by what we choose to fight for through participation or protest,” she wrote on her Instagram story.

LL Cool J says he won't be performing at Philadelphia's 4th of July celebration as long as the strike is ongoing with District Council 33.
