 Since the album 's release in early April , Carey had said publicly that she planned on embarking on a large worldwide tour in support of E = MC ² . In an interview with Billboard on March 28 , 2008 , Carey explained " It 's come up , and I 'm probably going to do it , but I don 't know exactly how we 're going to do it or when . I 'm thinking probably September . But I think it 's important to tour with this album , because there are so many songs that I really want to sing live , that I really enjoy . " Months later , in an interview with MTV News in July , Carey further addressed her plans of a tour : " We 're looking at November right now . Please don 't hold me accountable if it turns out to be December 5 or December 7 or January 18 ! " When asked to describe the tour 's theme , Carey explained " I 'm thinking elaborate . I like elaborate . We only do substantial . That 's what my jeweler says . I haven 't gotten the looks in mind just yet , but we 're going to figure it out soon enough . " Despite continued plans for a tour , and announcements made on The X Factor in United Kingdom in November , the tour was suddenly cancelled by early December . Tabloids and critics began heavily speculating that Carey had become pregnant , and had abandoned plans for a tour as a result . Many claimed to have seen Carey visiting a famed gynecologist 's office in Los Angeles . Additionally , Carey 's newly slimmed figure began to change , as she stopped her exercise routines and gained weight . Though Carey had eventually announced that she was pregnant with twins on November 28 , 2010 , over two years later , she admitted she had indeed been pregnant during that time period , and suffered a miscarriage . For that reason , she cancelled the tour , and lost the child only two months later .
