13 of the world’s most renowned female singers pose with song creators/producers LA Reid and Kenny “Babyface” Edmonds at Fashion Rocks to sing “Just Stand Up!”, the worldwide charity single benefiting Stand Up 2 Cancer at Radio City Musical Hall in New York City on Friday.

Keyshia Cole, Leona Lewis, Fergie, Ciara, Mariah Carey, Beyonce, Mary J Blige, Rihanna, Carrie Underwood, Miley Cyrus, Ashanti, Nicole Scherzinger and Natasha Bedingfield are all decked out in their black Stand Up To Cancer t-shirts.

All three major TV networks, NBC, ABC and CBS will create a roadblock at 8pm EST on Friday to broadcast the event. Hosts include Halle Berry, Jessica Alba, Sheryl Crow, Charles Barkley and Melissa Etheridge.

“For the first time we can envision the possibility of stopping cancer in its tracks,” the group said in its mission statement. “But just when science is on the verge of giving us the breakthroughs that can end cancer, the will and the funding to do so are disappearing from the national agenda and from our collective consciousness.”

Leona Lewis performs during the Closing Ceremony for the Beijing 2008 Olympic Games at the National Stadium in Beijing, China.

Jimmy Page and Leona Lewis performed the Led Zeppelin classic ‘Whole Lotta Love’ at the closing ceremony, while David Beckham was also on hand for the event.

In the original, recorded in 1969, Robert Plant sings, “I’m gonna give you every inch of my love.” But in the version that was sung, Lewis, 23, changed the words to “every bit” of my love. The band also agreed to a request from organizers to drop the third verse, which includes similar sexual innuendos, to fit in to the eight-minute performance.

British singing sensation Leona Lewis poses with an elephant stuffed animal in support of The Elephant Project, an organization to raise money and awareness for the Alzheimer’s Association.

The organization was started by David Niederhoffer, now 18, after his grandfather passed away from Alzheimer’s disease. There is a phrase that says “elephants never forget,” and in the fight against Alzheimer’s disease, Niederhoffer is striving for those affected by the disease to “never forget.”

Here’s how it works: Well-known celebrities pose with an elephant beanie baby and sign a special Elephant Project card, which are then auctioned off to raise money to fight Alzheimer’s disease. Each auction package comes with an 8×10 picture of the celebrity and the elephant, a signed card from that celebrity, and an elephant beanie baby. Such celebrities as Zac Efron, Adam Sandler, Julie Andrews, and MANY more have participated in the project. James Marsden, Julianne Moore and Jennifer Garner are pictured below.

Currently, over $11,500 has been raised for Alzheimer’s care, research and support! The Summer 2008 round of Elephant Project auctions began yesterday with five to six auctions going live each day until Sunday, July 27th.

For more information on the auction schedule and how to support the cause, visit ElephantProject.org.
