Here is the clip of an interviewer asking Christina Aguilera if she had any communication with Brtiney and her PR person shut it down immediately along with Christina saying she can't speak on it. She did say she is happy for Britney though which could be seen as her way of showing support, but Britney took it as shade and even that it made Britney look like a liar. I hope Christina Aguilera addresses this after she gets Britney's message. This could be resolved quickly with an apology or acknowledgment, but it seems there is still bad blood lingering between the two. All these years later...wow.
