The So So Def 20th Anniversary concert at The Fox Theater in Atlanta last night was certainly full of star-studded surprises.

Usher, Ludacris and Lil Jon rocked the stage with several songs from their reigning past, including ‘U Got It Bad’, ‘Lovers and Friends’ and their club smash ‘Yeah!’. A stripped back power performance came from Monica with ‘Love All Over Me’. The concert was indeed a historic night and everyone was in good spirits. Congratulations goes out to the entire So So Def family for making it this far! Now check out both performances below!
