  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.
