Mark Ruffalo has jumped into the latest Hollywood feud and is firing back at Kevin O’Leary after Shark Tank 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 his acceptance speech to condemn the Trump administration’s immigration policies.
“Kevin O’Leary why don’t you S**U. It’s fun,” the Avengers actor wrote. “You’ll go to any show and talk crap about any number of things and smugly expect us to listen to you, but you’ll dig into a real artist who eclipses anything you dream of doing to actually say something that resonates with 100s of millions of people around the world. It’s amazing the fantasy double standard Kevin O’Leary lives in.”
Ruffalo also took a dig at O’Leary’s latest acting role, adding, “You did great 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 a Fox News appearance.
“Half the people in politics that you piss off won’t buy your music anymore,” O’Leary said on Fox News’ America Reports on Tuesday. “Don’t be silly about it, but hey, they don’t listen.”
He added: “It’s the first lesson 101 for celebrities: When you rise, whether you’re a movie star, a music star [or] whatever, shut your mouth and just entertain.”
At the 2026 Grammys, Eilish won Song of the Year for Wild flower and used his speech to speak out against immigration enforcement, wearing an “ICE OUT” pin.
“Nobody’s illegal on stolen land,” she said, later urging fans to “keep fighting and talking and protesting,” before yelling “F**k ICE,” which played out on CBS.
Many artists, including Bad Bunny and Shaboozey, echoed similar sentiments.
