The concept of the Drake vs. Lil Wayne tour pits the two stars against each other in an app-based competition to see who receives the most fan support at every tour stop. One way to come out on top is definitely bringing out the big guest stars, like Lil Wayne did when he brought out 50 Cent and G-Unit.

The Young Money leader brought out the reunited group during the Hartford, Conn., concert on Wednesday (Aug. 13). Since Drake and Lil Wayne are going hit-for-hit, it makes sense that 50 Cent would end up performing his biggest song -- 'In Da Club.'

This wasn't just a big moment in the show's context. Lil Wayne and 50 Cent exchanged disses in the mid-00s but officially buried the hatchet when they appeared in photos together in 2012.
