The couple married in secret on April 4, 2008, but news of their wedding wasn't confirmed until the following October when Bey said "I'm married now" at a Manhattan listening party in the opening video montage of her "I Am ... Sasha Fierce" album, People magazine reported. But even then their relationship remained shrouded in secrecy.
When Beyoncé appeared on Oprah's Next Chapter in 2013 to promote her "Life Is but a Dream" documentary, Oprah said: "I remember the first time you were on the Oprah show, I told you, 'Don't go around telling people who you're dating.' I think you took that all the way. Don't tell people who you're dating, but you can tell people who you're married to, OK?"
