The Simmons sisters will be busy again this weekend as both Vanessa and Angela will attend the annual gala Dallas Rocks 2009: Diamond Dinner benefiting Diamond Empowerment Fund (D.E.F.) honoring Bush twins, Barbara Bush and Jenna Bush Hager.

Vanessa and Angela Simmons will present Bush twins, Barbara bush and Jenna Bush Hager with the Rising Star Empowerment Award. As we all know, Vanessa and Angela are nieces of the founder of the Diamond Empowerment Fund, Russell Simmons, who founded D.E.F. in 2007. Uncle Russ and Anthony Anderson of Law and Order are hosts of the event. Did you know that last year in 2008, the Dallas Rocks gala raised $250,000 benefiting D.E.F.? The organization helps to benefit CIDA (Community and Individual Development Association) and African Leadership Academy, both based in Johannesburg, South Africa. These kinds of gala dinners are not the only way for them to raise funds. Remember the Malachite Green Bracelet? The symbol of the cause itself has raised more than $650,000 for the fund to date. D.E.F. members include individuals in the diamond and jewelry industries and others who are committed to the empowerment of Africa.

Barbara Bush is the president and co-founder of Global Health Corps. She’s also active as a member of UNICEF’s Next Generation steering Committe. Her twin, Jenna Bush Hager is a teacher and a contributing correspondent for the Today Show.

The Bush twins won’t be the only ones receiving awards. Other honorees include Marilyn Auger, founder of the Marilyn Auger Family Foundation, a Dallas-based nonprofit that seeks to break the cycle of poverty. There’s also former NBA athlete, Dikembe Mutombo, who’ll receive an honor for the Dikembe Mutombo Foundation,which seeks to improve living conditions in his native, Congo.

The event is going to take place on November 14, 2009 from 6:30 P.M. to 1:00 A.M. at the Dallas Historic Union Station. If you decide to go there just to catch a glimpse of the Simmons Sisters, good luck to you. And just an insider info: Rev. Run and Justine Simmons are going to be there and it’s gonna be Rev. Run’s birthday on the same night of the gala.
