I have always thought the same thing. He is five or six years older than her and they were all kids. I could see that she maybe had a crush on him. She told him Brittany did, but I bet she did, too. However bitter and jealous she may be, she is really showing her maturity level the way she treats him. And if she thinks she is this much better than a former co-star, how the heck much better does she think she is than her fans???
If I were producing this show, she would be called in my office and harshly reprimanded for her rude treatment of one of their contestants. She has no right to treat him in such a way and I am disgusted with the "show" for allowing it. When he was thanking Adam last night, he took a moment to thank all the judges for their input. Christina was actually TEXTING on her cell phone while he talked, didn't even have the decency to pretend like she was paying attention. I backed it up and slowed it down to make sure I had seen it right, and sure enough she was. Blake noticed it to, and he looked at her absolutely disgusted! She is a complete wacko and a major embarrassment to the integrity of this program.
Her choice of dress last night should not have been approved, either. She looked very tacky. And to top it off, she went out there dressed like that to sing a Prayer song! Get real, woman!
