Are Elizabeth Olsen and Tom Hiddleston dating?

Rumours are flying that Elizabeth Olsen and Tom Hiddleston are dating.

Avengers stars Elizabeth Olsen and Tom Hiddleston have fuelled reports of a romance after enjoying a cosy break together in Oxford, England.

The actors, who will also play husband and wife in the upcoming Hank Williams biopic I Saw the Light, were first rumoured to have embarked on an off-screen relationship in May.

Now it appears there is some truth to the dating speculation after they were photographed walking arm-in-arm following a recent lunch outing in Oxford.

Representatives for Olsen and Hiddleston, 34, are yet to comment on the reports.

Olsen was previously engaged to actor Boyd Holbrook, but they called off their engagement in January.
