Mariah Carey has finally let husband Nick Cannon talk her down off her sky-high stilettos. “I got Mariah Carey, the high-heel queen, to put on some flats,” Cannon told listeners of his “Rollin With Nick Cannon” radio show this morning. But considering that she’s set to debut a new line of footwear, we’re not sure if the mommy-to-be will be able to keep her feet on the ground for long. On Cyber Monday, Carey will hit the airwaves to unveil her new lifestyle line for shopping channel HSN, which includes rhinestone-studded sandals, peep-toe platforms and a pair of cozy quilted winter boots (to satisfy Cannon, perhaps?). The exclusive collection also features crystal and butterfly-embellished jewelry, limited-edition fragrances and a special-edition copy of the singer’s hotly anticipated holiday album, “Merry Christmas II You.” Tune in to HSN on Monday, November 29th for your chance to score something from Mariah’s line!
