We have studied the interaction of vectors mesons within the hidden gaugeformalism and applied it to the particular case of the $\rho \rho$ interaction.We find a strong attraction in the isospin, spin channels I,S=0,0 and 0,2,which is enough to bind the $\rho \rho$ system. We also find that theattraction in the I,S=0,2 channel is much stronger than in the 0,0 case. Thestates develop a width when the $\rho$ mass distribution is considered, andparticularly when the $\pi \pi$ decay channel is turned on. Using aregularization scheme with cut offs of natural size, we obtain results in fairagreement with the mass and the width of the $f_0(1370)$ and $f_2(1270)$ mesonstates, providing a natural explanation of why the tensor state is more boundthan the scalar and offering a new picture for these states, which would bedynamically generated from the $\rho \rho$ interaction or, in simpler words,$\rho \rho$ molecular states.
