'Christmas at Rockefeller Center'
Lots of ladies top this year's annual tree-lighting extravaganza, including respected talents (Sheryl Crow, Annie Lennox) and reality-TV spectacles (Susan Boyle, Jackie Evancho). Mariah Carey should split the difference nicely; she's even got a bonkers new holiday album to promote. With Josh Groban, Jessica Simpson, Katherine Jenkins, Charice, and Kylie Minogue.
