Christina is trying to be nice to 'ol pal Britney Spears after years of feuding. Christina said "I wrote Britney a letter. It was very personal... I think she's a great girl... She's a sweet girl...", however Christina later added, "I have yet to hear back from Miss Brit. So, Britney, I'd like an answer. I'd like a response." Brrrr, the cold shoulder. Your first mistake was sending her a letter, everyone knows she can't read, secondly I'm surprised you where able to scribble your thoughts down on a piece of paper. Don't do it Britney, resist the dark side.
