Harry Styles stays at Taylor Swift’s AGAIN, surely they are at the leaving the toothbrush stage by now?

Harry Styles and Taylor Swift had a sleepover last night, we have photographic evidence and everything:

Last night the One Direction star was spotted making his way into Taylor's hotel for the second night on the trot.

OK, so we know it's not too unusual for couples to sleep in each others beds, but to be honest we are only just still getting used to this one.

Harry was snapped with the huge overnight bag slung over his shoulder arriving at Taylor's hotel at 11pm, an hour after she had arrived back from a recording session.

We don't know why he doesn't just start leaving his stuff there, sounds like they are almost definitely at the toothbrush stage.

Or at least at the stage where we can give them a questionable nickname.

We (or at least the good people of Twitter) hereby bless this couple Haylor! It totally works, right?

However, despite all the photos and overnight stays, some people are still convinced this is an elaborate publicity stunt.

If so, then 'publicity stunt' just went straight to the top of our Christmas list.
