Taylor Swift: Eyes for Tom

A month before splitting with Calvin, Taylor Swift had eyes for Tom Hiddleston ... or so it seems.

Check out this pic, taken May 1st, at the end of a pre-Met Gala dinner at Anna Wintour's house. Tay seems to be peering in the direction of an unsuspecting Tom, who's jawboning with Idris Elba.

Tom did a radio interview not too long ago (above) where he strongly suggests Taylor made the first move ... at the May 2nd Met Gala.

As we reported, we're told Calvin believes his ex and Tom were together weeks before they called it quits on June 1st.
