Mark Ruffalo has sharply criticized Kevin O’Leary after the Shark Tank investor attacked Billie Eilish for her political comments at the 2026 Grammy Awards. The exchange quickly went viral and added fuel to the ongoing debate over celebrity activism.
During the Grammys on February 2, 2026, Eilish won Song of the Year for “Wildflower.” In her acceptance speech, she made a strong statement about immigration and Indigenous rights. Her comments sparked immediate reaction online and across media.
O’Leary addressed the moment during a Fox News appearance soon after. He argued that celebrities should avoid political messages and focus on entertaining audiences. He warned that political statements can push fans away and harm careers.
Ruffalo responded on Threads on February 5 with a blunt and personal post. The actor accused O’Leary of hypocrisy and defended Eilish’s right to speak out. His message spread quickly and was widely covered by major entertainment outlets.
In his post, Ruffalo said O’Leary frequently shares his own opinions on television while criticizing artists for doing the same. He praised Eilish as a “real artist” whose words connect with people around the world. Ruffalo also mocked O’Leary’s recent acting role, suggesting he had exposed his own double standards.
The clash highlights a long-running argument in pop culture. Some figures believe award shows should stay apolitical. Others argue that artists have always used their platforms to address social and political issues.
Eilish has not directly replied to O’Leary. However, her brother and collaborator Finneas has reportedly pushed back against critics in related discussions. Fans and commentators remain divided.
As debate continues online, the Grammys moment has clearly reached beyond music. The exchange between Ruffalo and O’Leary shows how celebrity speech remains a flashpoint in entertainment and politics.
