Nick Cannon obviously spared no expense while shopping for Mariah Carey’s Christmas gift. On Wednesday, Carey posted a picture of the new Rolls Royce Phantom that her husband bought her over the holidays. The singer captioned the photo with a tweet that reads, quote, “Still getting over my Christmas gift from @NickCannon. License plate:mommyMC.” Nick Cannon and Mariah Carey have been in the news of late, as it was recently reported that the couple is expecting twins. The children, which will be their first, are due sometime this spring.
