  We use the AdS/QCD distribution amplitudes for light mesons to calculate the
transition form factors for B to $\rho$, $K^*$ decays. These form factors are
then utilized to make predictions for the semileptonic $B\to\rho\ell\nu$ and
dileptonic $B\to K^* \mu^+\mu^-$ decays. We compare our predictions to the
experimental data from BaBar and LHCb.
