Ed Sheeran has said numerous times that he and Taylor Swift are just friends, and she probably wouldn't be interested in dating him anyway because he's not her type.

But, as the name of their duet suggests, perhaps "Everything Has Changed."

A witness told E! Online that on Feb. 19, the night before the Brit Awards in London, Sheeran arrived at Swift's hotel and went to her room where he stayed until around 4 a.m. When he left, he got into the same car that Swift had used earlier in the day and was driven away.

So is this something new between them, or the rekindling of an old flame? Sheeran and Swift "briefly dated" last spring, a source told E!, and said that they had "great chemistry" together.

If the two are interested in a romance, it certainly won't have to be a long-distance one: Sheeran's opening for Swift on her upcoming Red tour.

Of course, there is one potentially awkward thing about the two of them getting together: Sheeran's good friends with Swift's ex, Harry Styles.
