Ed Sheeran -- My Ex Is No Factor

Ed Sheeran always looks a little uncomfortable, but he kicked it up a notch when he ran into his ex-gf Ellie Goulding. Y'know ... the ex he says cheated on him with one of those 1Ders.

Typical, right? Boy meets girl, girl cheats on boy with other boy, boy gets super awkward hug from girl ... while strangers watch.
