It’s pretty safe to say that Jack White had the best day ever on Friday. As if releasing a new album and playing the national anthem at Opening Day for the Detroit Tigers wasn’t enough, White kicked off his Supply Chain Issues tour with a hometown show in Detroit, and capped the evening off by proposing to girlfriend, Olivia Jean, on stage, and then marrying her in front of a sold-out crowd at the Masonic Temple moments later. White brought Jean onstage to help him perform White Stripes favorite "Hotel Yorba," and just as the song was about to end, White popped the question to a completely shocked Jean, and audience. She of course said "yes," and White got to sing a line in the song that was absolutely fitting: "Let’s get married in a big cathedral by a priest." Not only is Jean his girlfriend, but she is also opening for his Michigan shows on tour. Jean, a Detroit native, is an artist on White’s record label, Third Man Records.
