The 'Gossip Girl' actress and the 35-year-old hunk - who have been dating since October - were spotted in the west coast city of Vancouver where they went out for dinner with his family on Monday night (19.12.11).
The following day the romantic pair were spotted stopping at Benny's Bagels, where they were "really friendly" but kept to themselves.
It is not the first time Ryan and Blake - who split with Leonardo DiCaprio after five months of dating earlier this year - have been spotted out and about; in October they enjoyed an intimate dinner in Boston while he was there working on movie 'R.I.P.D'.
The pair initially met on the set of superhero movie 'Green Lantern' and were keen to try out something more serious after she split from 'Inception' star Leonardo.
A source said: "They became good friends on the set [of 'Green Lantern']. Now they're both single and trying it out. They're seeing each other casually."
Since Ryan separated from his wife Scarlett Johansson after two years of marriage in late 2010, he was linked with several famous beauties including Sandra Bullock, but he joked he couldn't have dated so many women as was claimed because he is not "potent" enough.
The Canadian star previously said: "Right now I seem to be on a speed-dating mission - at least according to those stories that are going around at the moment. Even my mom is confused. No man is potent enough to be able to go through as many women as that in such a short amount of time like I allegedly have!"
