I was re-reading the DM's article, they are backtracking a little aren't they?

It's not a fact anymore, they are rumoured now, and it's USWeekly (from its first article) that says they hooked up but they are keeping it casual. And the rumoured romance started after she broke off her engagement in January.
Even the caption on Pap Night'15's photo is interrogative.
"Romance? Elizabeth is rumoured to be dating Tom Hiddleston and was most recently seen with him in London on July 23"
