Check This Out: Bald Beauty? Now hair this: Christina Aguilera may be losing her locks. One well-placed follicle flunky tells us the singer's classy, curly new 'do is designed to cover up her bald spots. "They don't know if it's alopecia, the disease, or if it's from wearing extensions all these years," says our spy. "Her hair is falling out. Her new look is supposed to cover up the hair that she's already lost." But Aguilera's rep flatly denies the allegations: "It's absolutely not true. There is nothing wrong with her hair." - That's from Page Six in the New York Post today
