The NSYNC star married longtime boyfriend Michael Turchin last month in Los Angeles, and according to People magazine, the happy couple walked down the aisle to Xtina's Bionic ballad, I Am.
Unfortunately, the Dirrty diva couldn't be there to sing it herself, so R&B crooner Kelly Price stepped in instead.
The wedding, which was planned by Sharon Sacks (the planner behind the Kimye nuptials) included celebrity guests like Jamie-Lynn Sigler and Lisa Vanderpump, and featured supermodels instead of flower girls.
