We study the di-photon rate in Higgs decays within singlet extensions of the supersymmetric standard model. In particular we point out that light charginos as well as a light charged Higgs can significantly contribute to the corresponding partial decay width, allowing for an explanation of the experimental indication whithin a natural supersymmetric model. This is in contrast to the ‘light stau scenario’ proposed within the framework of the MSSM which requires a large amount of electroweak fine tuning
