Lambs and Beliebers, rejoice!
Mariah Carey and Justin Bieber's "All I Want for Christmas Is You" video has arrived! In the remake of Carey's 1994 hit, the 41-year-old shows off her svelte post-baby bod in a short, sexy holiday costume. (Carey lost 30 pounds since giving birth to Moroccan and Monroe in April.)
