The power of Taylor Swift is real. So much so that While attending the US Open men’s tennis final on Sunday (September 8), Taylor Swift and her boyfriend Travis Kelce were shown enthusiastically singing along to the Darkness’ 2003 hit, “I Believe in a Thing Called Love.” The video of the couple rocking out to the song – which was even shared on X by the official US Open account – has since gone viral, and it has subsequently propelled the song to No. 1 on the US iTunes Rock Chart.
