After the 2012 MTV VMAs, Lil' Wayne rocked the mic at Playhouse where he celebrated the released of his Dedication 4 mixtape and his new line of headphones for Beats By Dre.  Deets inside....

Last night at Playhouse in Hollywood, Lil' Wayne hit the stage to debut his new custom red Beats by Dr. Dre Pro headphones. Yep, they are the ones he was rocking and jamming to DURING the VMAs last night.  He also performed tracks off his Dedication 4 mixtape alongside his YMCMB crew.

Drake was in attendance and got the crowd hyped.

Dre, Forbes' #1 Hip Hop Cash King who banked over $110 in cash off his line of headphones last year, and DJ Drama were both at the performance.

Bad Boy Machine Gun Kelly gave the glossy red headphones his approval.

LMFAO's Sky Blue was there too.
