The Jonas Brothers concert at the Ross school was a big success, and the highlight of the summer for many the tweenster.  Peter Cook wasn't going to let Christie in on all the fun of playing "hip parent".  He showed up at the concert with his daughter, while Christie was there with son.  No word on whether the two had a meet up, but more importantly, I'm in love with her outfit...where oh where can I get my own pair of purple sneakers???
