Abstract In this letter we calculate the emission of gravity waves by the binary pulsar in the framework of five dimensional braneworlds. We show that the presence of additional degrees of freedom, especially the 'gravi-scalar' leads to a modification of Einstein's quadrupole formula. We compute the induced change for the binary pulsar PSR 1913+16 where it amounts to about 20% which is by far excluded by present experimental data.
