ONE FOR JASMINA: Was Rihanna's sincerity an act?

A leukemia-prone child trembled the heart of Rihanna Fenty and sparked a "girlfriend" relationship between the 6-year-old and the superstar.

In January of this year, Jasmina Anema died of her life-long disease and Rihanna fans poured in on her account, but Jasmina's mother, Thena Anema, wonders if Rihanna's sincerity was falsified (said via People.com).

As posted on the Official Twitter Account for Jasmina supporters, an author acknowledged: It has been a month since Jasmina's passing. Still not even a card or text message from Rihanna. Did she use my child for a publicity stunt?

Anema, in an email to People, said that she did not pen the tweet herself, but that she had wished Rihanna reached out to her in some sort of way.

Days after Jasmina's death, however, Rihanna released this statement to the Associated Press: She was a very free, fun spirited little girl.... I always remember she wouldn't sit still. She was always running around, always had a smile on her face.

Although Anema has appreciated Rihanna's work, Katharina Harf of DKMS Americas suggests that Rihanna has worked genuinely for the cause: Last year she recruited over 5,000 bone marrow donors to DKMS – resulting in lives saved. She is relentless in her campaign to help children in the fight against leukemia and continues to urge her fans and people around the world to register with DKMS, as stated in People.com's original post.
