PINK performs the song “I Don’t Believe You” on possibly my favorite episode of the Oprah Winfrey Show. The singer, one of the best-selling artists of all time, has sold more than 40 million albums worldwide, talks candidly about her marriage to Carey Hart, who she met at the X Games in 2001. During their long separation in 2008, the couple sought marriage counseling in hopes of reconciliation. In February 2010 on Oprah, Pink confirmed that she and Hart were back together. On June 2, 2011, Pink had their daughter, Willow Sage Hart.  Pink maintains it was through writing this song, and sharing it with her husband, how important it was for them to stay the course in their marriage rather than start over again. “That’s what relationships are for — to teach us about ourselves, and to help us grow,” she says. “I’m glad you’re back together,” Oprah told the singer. This past January (2012), Pink and Hart celebrated six years of marriage: ”I haven’t killed you yet,” Pink jokingly Tweeted her hubby on their anniversary, “But give it time darling.“
