Mark Ruffalo waded into Hollywood’s latest feud, hitting back at Kevin O’Leary after the Shark tank The star slammed Billie Eilish for speaking out against ICE at the 2026 Grammys.
The Oscar-nominated actor took to Threads to defend the Grammy winner, who used her acceptance speech to condemn the Trump administration’s immigration policies.
“Kevin O’Leary, why don’t you have sex. It’s hilarious,” said the Avengers the actor wrote. “You’ll go on any show and say bullshit about any number of things and smugly expect to be listened to, but you’ll discover a true artist who eclipses everything you ever dreamed of doing for saying something that resonates with hundreds of millions of people around the world. It’s astonishing the fantastical double standard that Kevin O’Leary lives by.”
Ruffalo also criticized O’Leary’s recent acting role, adding, “You did well in Marty Supreme,” referring to his performance as ruthless businessman Milton Rockwell in the Josh Safdie-directed film.
The clash began after O’Leary warned celebrities against mixing politics and entertainment during an appearance on Fox News.
“Half the people in politics that you piss off won’t buy your music anymore,” O’Leary said on US Fox News Reports Tuesday. “Don’t be stupid about it, but hey, they’re not listening.”
He added: “It’s the first lesson 101 for fame: as you rise, whether you’re a movie star, a music star [or] whatever, just shut your mouth and have fun.
At the 2026 Grammys, Eilish won song of the year for Wildflowers and used his speech to denounce immigration measures, wearing an “ICE OUT” pin.
“No one is illegal on stolen land,” she said, later urging fans to “keep fighting and speaking out and protesting,” before shouting “F**k ICE,” which aired on CBS.
Many artists, including Bad Bunny and Shaboozey, have echoed similar sentiments.
