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.”

After spending two romantic weeks together in The Bahamas, newlyweds Mariah Carey and Nick Cannon topped off their vacation with a trip to Walt Disney World Resort on Tuesday in Lake Buena Vista, Fla.

They even got cutesy with Mickey and Minnie Mouse at Disney’s Grand Floridian Resort and Spa!

Mariah, 39, and Nick, 27, enjoyed some of the theme parks’ rides including the Rock ‘n’ Roller Coaster Starring Aerosmith, the famous indoor coaster Space Mountain (Nick’s favorite ride), and the Twilight Zone Tower of Terror (Mariah’s favorite.)

Mariah Carey grabs hold of her husband Nick Cannon in the latest cover photo spread in Elle. Here are a few more interesting quotes pulled from the article:

On Nick, who’s ‘motivated by faith’: “We really do share a similar spiritual outlook on life… Even though people have their own fears about ‘Was I in a relationship before this, was I not in a relationship before this,’ to me, I wasn’t in a real relationship; it was more of a friendship and a working situation.”

On the importance of her future kids living in ‘reality’: “You can get caught up in Hollywood-land or celebrity-land, and that’s maybe not the best thing for kids, ’cause they didn’t ask for it. Speaking for myself, I don’t know that I always felt safe and secure [as a child] — and that’s nobody’s fault; we’re not mudslinging or trying to slay anybody — but truly I really feel like it’s very important to be responsible and to think, Well, maybe if I do this it’s not the best thing for my child. You have to take a backseat a little bit, and as someone in the public eye, you’re not used to doing that…. I couldn’t imagine anybody that I’ve ever met being a better dad [than Nick].”

Mariah Carey talks about her new body, new record and hot new man in the August 2008 issue of Elle magazine. Here are some of the key points Mariah drove home:

On her unhappy past: “When I was in an unhappy place in my life, I always wanted to be kidnapped. I just wanted a way out, but didn’t have one.”

On Nick Cannon saving her: “He sort of kidnapped me and took me on a helicopter ride. Then he re-proposed. (His first proposal had taken place on Mariah’s roof in Manhattan a couple of evenings prior and involved the hiding of a 17-carat diamond ring inside a candy ring pop.) They’ve been calling me Cinderella since I first started out, so, of course, being Cinderella… Most people would think, Okay, please! This doesn’t happen in real life.”

On keeping her and Nicks’ romantic involvement on the down low: “We really kept the whole relationship aspect of it quiet. Therefore, we didn’t really ‘date,’ you know what I mean? Because that would have been not quiet or private. I think we didn’t want to give people a chance to be like, ‘What are you doing? What are you talking about? This is so quick… are you sure?”

On her racial ambiguity naturally attracting her to Barack Obama as a presidential candidate: “I can relate a lot to so many of the stories he tells. Clearly I am not the political analyst of the ages, but this is something that hits me on a deeper level than anything I’ve ever experienced growing up… I would be honored if he wanted me to be involved in any way. Right now I’m kind of watching from the sidelines.”
