In a video he posted to Instagram on Sunday, Urban, 51, wrote, “Every now and then you hear a song that you love and wish you’d written…. and a HUGE thx to my band as well – we didn’t get to rehearse so…. this is us fully winging it.”
Swift, 29, caught wind of the cover and fangirled in her own Instagram Story.
“Keith Urban covering ‘Lover’ flawlessly,” she wrote. “I am screaming. This is so beautiful.”
Swift’s seventh album, also titled “Lover,” dropped on Aug. 23. On Sunday, it officially became her sixth album to rocket to No. 1 on the Billboard charts.
According to Billboard, “Lover” sold more in five days than any other album in its first week since Swift’s 2017 record, “Reputation.”
“Lover” features a whopping 18 tracks, including several songs about her three-year relationship with British actor Joe Alwyn, according to People.
“It’s the first album of mine that I’ve ever owned,” she tweeted of “Lover,” “and I couldn’t be more proud.”
