J. Lo and Iggy will be seated in the front row next to another highly anticipated performer -- Taylor Swift, who will be singing her hot single "Blank Space" live for the first time.
The new single from 1989 just appeared at No. 1 on the Billboard Hot 100 list, knocking off Taylor's other hit "Shake It Off" and making Taylor the first female artist to replace herself at the top of the charts.
The 2014 American Music Awards airs live Sunday, Nov. 23 at 8/7c on ABC.
