Abstract : We investigate Bose-Einstein correlations (BEC) in W-pair production at $\sqrt{s}\simeq 189 \GeV$ using the L3 detector at LEP. We observe BEC between particles from a single W decay in good agreement with those from a light-quark Z~decay sample. We investigate their possible existence between particles coming from different W's. No evidence for such \interW\ BEC is found.
