Christina Aguilera is searching for a “pretty, young, sexy, hip” young lady as a caretaker for her bouncing baby boy, due on January 10th, 2008. Sexy and hip? Is she looking for a nanny or America’s Next Top Model?

“Christina figures that the nanny will always be with her, so she wants to make sure she’s cute and fun,” a spy spills to Star Magazine.

“She wants a lighthearted and interesting girl who’s also really easy on the eyes.”

Christina reportedly enjoys being around supermodel types.

“She doesn’t want some old hen bossing her around.”

Christina has already interviewed several nanny prospects and hopes to make a final decision by New Year’s Day.
