KIIS FM hosted its annual Jingle Ball Christmas concert in Anaheim this week. And as usual the popular LA station got some big names to come out to entertain their listeners. JT, being one of them, had quite a busy day yesterday. He picked up two Grammy nominations for pop vocal album of the year and album of the year. Justin's SexyBack partner Timbaland also performed along with Nelly Furtado, Bow Wow and JoJo.
