Taylor Swift, Stop These Late Night Rendezvous With Ed Sheeran RIGHT NOW!

Oh no, not again! Taylor Swift has left a trail of exes like blown roses over the cultural landscape, but when she goes after our very own VH1 You Oughta Know artist Ed Sheeran, that's where we start getting all mother hen up in here!

According to reports from E!, the pair spent the night before the BRIT Awards on February 19th together in Swift's hotel suite. "He stayed in [her' room, just the two of them, until around 4 a.m," says a witness, who also added that he looked "very happy." Errrr, ok...

"He looked very pleased with himself," the insider continued. According to the news outlet, the two musicians "briefly dated last spring. He thinks she is really cute, and they have a great chemistry together." He contributed parts to her latest album Red, and more recently she took to Twitter to send him an extra-gushy birthday wish. "So. One of my favorite human beings on the planet turns 22 today. I hope @edsheeran has the most perfect show in LA tonight! HAPPY BDAYYYY."

It's hard to say whether or not the two are just close professional friends (he is her opening act on her tour this year, after all), or if there's something more. Who knows, it could very well be both!
