Bono knows who he’s backing in the battle between Bruce Springsteen and President Donald Trump.

Asked if he was rooting for the rock star or the U.S. president during a Tuesday night appearance on “Jimmy Kimmel Live!,” the U2 frontman had the crowd roaring as he smiled and said, “I think there’s only one ‘Boss’ in America.”

Kimmel also got Bono to address one of Trump’s recent Truth Social rants, where he accused the Irishman of being paid to endorse Democratic presidential candidate Kamala Harris... despite the fact Bono never weighed in on the 2024 election.

Before setting the record straight, the “Sweetest Thing” singer winked at Kimmel’s continuous clash with Trump, as he told the late-night host, “I don’t want to cut in on your action, because I know the president at 1 a.m., or 1:30, or whatever that was, is usually thinking about you.”

But the president seemed to have Bono and not Kimmel on the brain earlier this month, when he baselessly claimed the human rights activist and singer, along with Springsteen, Oprah Winfrey and Beyoncé, had accepted money in exchange for publicly supporting the former vice president.
