It’s Mariah Carey Day around the world, as her album E=MC? drops today with much fanfare. Yesterday our favorite diva showed up on Oprah to give the talk queen a personal tour of her massive NYC house. Our favorite spot in her lair? Mariah’s effing lingerie closet, which you can gawk at in the video clip above. She really IS just like us common folk! Mimi has like, a billion sexy nighties, which is a good thing because it’s rumored that she might have a new boy toy just waiting to see her strip down to something more comfortable. The singer’s been spotted recently getting close with the multi-talented hottie (and heartbreaker) Nick Cannon. Sure, her rep’s denying that they’re together, but they were just in Vegas last night acting chummy! And let’s be real – there’s nothing like celebrating a hit album with a little booty call, right?
