Of all the VIP guests and historic moments at Drake's OVO Fest last Monday (Aug. 5), Diddy and Ma$e's reunion was easily one of the biggest highlights of the night. The Bad Boy boss and his former golden child took it back to the late '90s by performing 'Feel So Good' and 'Mo Money Mo Problems' in front of the sell-out crowd.

In their latest vlog from the Toronto festival, Revolt TV grants us a unique look at Diddy and Ma$e's reunion from backstage. Nine years may have passed since they last linked up -- on Ma$e's 2004 LP, 'Welcome Back' -- but the old friends were sharing a laugh like the 'Harlem World' days were just yesterday. You know what they say: Bad Boy for life.
