Is she really dating Glen
Wikipedia does not say if she is dating Steven Yuen (Glen): http://en.wikipedia.org/wiki/Lauren_Cohan
According to this Rolling Stone article, they are not dating:
Lauren says, “There are entire websites dedicated to the proof that Steven and I are in a real relationship. Which is always funny, because it's not.”
So even though they are often seen together in pubic, they are not dating. Just friends.
