The "brunette with blonde highlights" sighting seems to have been on 25.01 (and some people thought it was Kat Dennings!). It could I suppose have been EO if she went to London before heading on to Paris. After 25.01 and in early feb I don't see from the bycycle any mentions of him with EO or anyone.

He went to Bafta dinner on 4.02.15 and on weekend of 7/8 Feb he was seen in Suffolk (twitter I think - which I can't find but I remember thinking it was sad that even in a little seaside town he can't get away from it all).
