Christina Aguilera Receives a Special Achievement Award: Although the diva arrived just before the show was set to begin, her mere presence was definitely one of the biggest highlights. Dressed in a fitted black dress with lace cutouts that highlighted her killer curves, Christina took the stage (rocking pink and purple tips in her hair) to accept a special achievement award after an impressive video tribute honoring both her incredible career and her work in philanthropy played on stage. "I share this award with all my fellow fans who are using their voice for good," she said with pride. Oh, and did we mention she received a standing ovation from the entire theater? Werk, Christina!
Don't forget to tune in Friday, Sept. 21 when the entire show is broadcast on NBC at 8 p.m. ET / 5 p.m. PT!
