Justin Bieber continues to trek on (with Post Malone in tow) for his "Purpose" world tour in support of his recent album. The singer, who sells out stadiums just about anywhere, hit Atlanta last night, where he brought out a special guest.
Justin Bieber took it back to 2010 with a performance of his hit single "Baby" with Ludacris-- no doubt day one Bieber fans were wetting their pants. This isn't the only surprise guest he's brought out while on tour, while at the Staples Center in L.A., Bieber brought out Chance the Rapper and Big Sean.
The sound quality on the video is shit, but watch above. Bieber has his second show at Atlanta's Philips Arena tonight, before heading to St. Louis.
