Christina Aguilera gave one of the most anticipated performances on the AMA's last night and I'm sad to admit that I was not impressed. This year marks the 25th anniversary of Whitney Houston's film The Bodyguard and Christina was chosen to pay tribute to the late singer by singing a medley of songs from the movie soundtrack. I'm sure we can all agree that paying a tribute to one of the greatest artists of all times is a bold move on anyone's part, but if there was anyone who I thought could deliver, it was Xtina. I can't help but think that maybe I set my expectations too high.....or maybe those lip injections restricted her vocals??
