Billie Eilish made a surprise appearance on stage with Green Day on Thursday to kick off one of two star-studded concerts in Los Angeles put together to raise funds for people affected by deadly wildfires in California this month.

One day before Donald Trump's inauguration as the 47th president, Green Day delivered a pointed lyrical jab at Elon Musk during their concert.

Green Day are currently in South Africa for their first shows ever in the country. Frontman Billie Joe Armstrong didn't waste the opportunity to bite his thumb at its wealthiest and most well-known son during their gig in Johannesburg last night, when he changed a line in American Idiot to let the Tesla CEO know his thoughts.

Green Day's frontman Billie Joe Armstrong is publicly considered a bisexual icon, a label he proudly embraces.

Pop stars, first responders, rock musicians, and wildfire survivors gathered for FireAid on Thursday night, a benefit concert to raise funds and share.

Green Day have taken lyrical aim at Elon Musk while performing in his home country of South Africa. The band’s frontman Billie Joe Armstrong reportedly switched a line in their 2004 hit “American Idiot” from “I’m not a part of the redneck agenda” to “I’m not a part of the Elon agenda.”
