Rapper Jay-Z will join superstar entertainers Lady Gaga and Christina Aguilera in auctioning off items to benefit Mary J. Blige’s Foundation for the Advancement of Women Now (FFAWN). 

Jay is offering an internship at his music management and publishing company, Roc Nation, for auction. Aguilera donated tickets to The Voice, a music competition television show she appears on as a coach alongside Cee Lo Green. Gaga donated passes to a meet and greet at her next upcoming Good Morning America appearance. Funds raised will be donated to the organization, which was created in 2007 by Blige and Steve Stoute in order to “inspire women from all walks of life to reach their individual potential.” 

Bidding begins now and ends June 1 at CharityBuzz.com/FFAWN.
