NEAT: NICK JONAS TO REWARD DIABETES PATIENTS.

Nick Jonas is to reward fellow diabetes sufferers for the good work they do in their community - by meeting them in person to hand over a charity cash prize. The Jonas Brothers star, who suffers from the illness, is teaming up with Bayer Diabetes to launch the Give Back Simply Win competition.

The singer is calling for fans who have diabetes to submit an application detailing how they are benefiting their local community. Jonas will then help to hand-pick three grand prize winners, who will meet the star and choose a charity of their choice to receive a $5,000 donation.

KELLY ROWLAND VISITS JASMINA, THE KID DYING FROM CANCER THAT RIHANNA IS TRYING TO HELP GET BONE MARROW.

Jasmina Anema, the spunky New York City girl who desperately needs a bone marrow transplant, loved the girly pink cupcakes and the Hello Kitty bicycle she got on her 6th birthday Wednesday. But she was "over the moon" when Grammy-winning singer Kelly Rowland sang "Happy Birthday" to her in her hospital room at NYU Medical Center.

"Kelly made me feel like a princess," Jasmina told PEOPLE Wednesday. "She made me feel so special."

Rowland had as much fun as Jasmina, who has a rare and deadly form of leukemia. "She made my day, to be quite honest," Rowland told PEOPLE. "It felt like a slumber party. She's so precious. She has such a beautiful spirit."

The former Destiny's Child star spent more than two hours with Jasmina and her best friend, Isabelle Huurman, 5. The trio frosted cupcakes, named Jasmina's new stuffed dog, Jazzilicous, and talked about The Little Mermaid's Ariel. "I'm 28 and I still love mermaids," Rowland told Jasmina, who was dressed in a tutu for her birthday bash. More at PEOPLE...

Rihanna is stepping forward to help a 5-year-old New York City girl find a bone marrow donor – the second time in a year that the Grammy Award winner has helped a leukemia victim seek a match.

"When I saw the video of Jasmina it broke my heart. It is so unfair that for a black patient it's so much harder to find a bone marrow match," the singer tells PEOPLE exclusively. "Jasmina has acute leukemia and she needs a bone marrow transplant to live."

In February 2008, Rihanna helped another female, New Yorker Lisa Flynn find a match by putting out a call for donors on PEOPLE.com.

"More than 5,000 donors came forward," says Katharina Harf of DKMS, the world's largest nonprofit marrow donor center, which is helping to find a match for Jasmina. "Rihanna has already helped DKMS save many lives," says Harf. "Now we can count on her again."

Hopefully she can still work on this project now and doesn't let the domestic issue stop her.
