Mariah Carey was in the holiday spirit on Friday to tape a performance for the Disney Christmas Day Parade. She joined Ryan Seacrest in Orlando to belt out holiday hits from her new album Merry Christmas II You, along with her classic "All I Want For Christmas Is You." Mariah was surrounded on stage by ballerinas, candy canes, Santa, and Disney characters, but her growing baby bump stole the show. Since confirming her pregnancy, the mom-to-be has kept quiet about twins rumors, but she did share that she's feeling extra festive this year. She scored the number-one spot on Billboard's Adult Contemporary chart this week with "O, Santa," and just released the video for "O Come All Ye Faithful/Hallelujah Chorus."
