British singer Ed Sheeran spent most of the night Feb. 19 with Taylor Swift.
A witness tells E! News that the night before the 2013 Brit Awards Ed arrived at Taylor's hotel and went straight to her room. From there, the two "stayed in the room, just the two of them, until around 4 a.m."
When Ed left the hotel, a witness saw him looking "very happy."
Another source says Taylor and Ed "briefly dated last spring. He thinks she is really cute and they have a great chemistry together."
