  The phi-meson leptonic widths, Gee and Gmm, are obtained, respectively, from
the e+e- forward-backward asymmetry and the muon cross section around the
phi-mass energy. We find Gee=1.32&#8853;0.05&#8853;0.03 kev and sqrt(GeeGmm)=
1.320&#8853;0.018&#8853;0.017 kev. These results, compatible with Gee=Gmm,
provide a precise test of lepton universality. Combining the two results gives
G_lept=1.320&#8853;0.023 kev.
