We investigate the Bs\ensuremath→\ensuremathμ+\ensuremathμ^\ensuremath- decay in the presence of a light stabilized radion in Randall-Sundrum model. The branching ratio BR(Bs\ensuremath→\ensuremathμ+\ensuremathμ^\ensuremath-) in the standard model is found to be 3.17\ifmmode×\else\texttimes\fi10^\ensuremath-9 (two order smaller than the experimental upper bound) and raises the question whether some new physics can play a crucial role or not. We found that for a reasonable range of parameters (i.e. radion mass m_\ensuremathφ and radion vev ⟨\ensuremathφ⟩), the above deficit between the experimental bound and the standard model result can well be accomodated. Using this upper bound on BR(Bs\ensuremath→\ensuremathμ+\ensuremathμ^\ensuremath-), we obtain the lower bound on ⟨\ensuremathφ⟩.
