Well, who can 4get the kiss...but i can't say it was my fav...she didnt sing one of her own songs. The NFL performence really sticks out to me cuz it was the first time she had done a show of her music in like a year. That was an awesome night! But for my fav. i'll have to go with her TRL performences of 'MATM' and 'Boom Boom'.
Leno. That's the only time MATM was live, and I loved it. That, to me, is her best performance. All of the lipsank crap, doesnt even count as a performance as far as I'm concerned.
