Justin Bieber's Purpose tour has made its way to Atlanta, and the Canadian singer kicked off the series of shows with a bang last night. Not only did Bieber run through his massive amount of hits, but he also brought out his friend Ludacris to perform their 2010 smash, "Baby." As expected, the crowd went absolutely crazy when Luda touched the stage, as the rap veteran and Bieber fed off of each other's crazy energy throughout the performance.

To this point, Bieber's Purpose tour has been completely turnt up, with Post Malone killing as the opener and Kanye West going ham in the crowd during a number of the Los Angeles shows.
