  We build on the success of AdS/QCD in predicting diffractive $\rho$ meson
production to obtain the transition form factors for B decays to light mesons.
Consequently, we predict several observables associated with $B\to \rho\ell\nu$
semileptonic and $B\to K^*\mu^+\mu^-$ dileptonic decays. Our predictions are
compared to the available experimental data.
