Diddy and Mase Reunion 'Mo Money, Less Problems"

The particular 90's were on plus popping again Friday evening in L. A. throughout Dr . Dre's pre-Grammy Celebration... but nothing was cooler compared to Puff Daddy reuniting onstage with his former protege Ma$e.

Diddy and Ma$e mortally wounded a stellar set of the songs including "Been Across the World" and "All Regarding the Benjamins" at the Belasco Theater... but their rendition of "'Mo Money, 'Mo Problems" had been off the charts.

Eminem strike the stage later at night with Dr . Dre... who also reunited with Blackstreet to perform "No Diggity. inch

It was all that and a handbag of chips.
