Rapper/entrepreneur Jay-Z is just one of several celebrities set to take part in an auction benefitting Mary J. Blige’s nonprofit organization Foundation for the Advancement of Women Now (FFAWN).

As part of the auction, Jay-Z will be offering the opportunity to intern at his entertainment/record company Roc Nation. On top of Jay-Z’s Roc Nation internship, singer Christina Aguilera will be donating tickets to The Voice for the auction and pop star Lady Gaga will auction off a meet and greet at an upcoming Good Morning America appearance.

The auction will be held through Charity Buzz, a luxury auction site that specializes in celebrity auctions.

Bidding for Mary J. Blige’s FFAWN auction starts now and will end on June 1, 2011. For more information and/or to make a bid visit CharityBuzz.com/FFAWN.

Formed in 2007, FFAWN was created by Mary J. Blige and Steve Stoute to “to inspire women from all walks of life to reach their individual potential.”

This marks the second time in a matter of weeks that Jay-Z has taken part in a celebrity auction. In March, Jay-Z auctioned off a pair of courtside Knicks tickets to benefit the Stephen Gaynor School in New York City.
