Aguilera Gets In Line?

(Photo: Splash News Online) Christina Aguilera may soon join the celebrity clothing line club, that is, if Sir Phillip Green has his way with her.

Green, British designer of Topshop fashion house, wants the pushing-30 singer to craft a few ensembles for his hot label.

After all, Green proved his keen fashion intuition last year by enlisting supermodel Kate Moss for a best-selling collection.

"Sir Philip has started talks with Christina and hopes to sign a deal soon. She has visited his offices in London and they are thrashing out the details," sources report.

"Philip loves her style and believes she would add something new to Topshop."
