ady_fa14 met Eddie Redmayne at Café de Flore in Paris. She published the photo this
monday, but didn't confirm the date, it's possible that this happened earlier this month,
when Eddie and Hannah were in Paris (I try to find out when)
Update 3 May, 2016:
Most likely the photos were taken on 19th April. Here are a few photos of Eddie and Hannah in Paris.
Eddie wore the same outfit. Thanks to Ieva for the info and Nadezhda for the photos.
