Dianna Agron and Alex Pettyfer Aren’t Engaged, But They’re Definitely a Couple

Dianna Agron recently denied engagement rumors and though we totally believe her — she blogged about it, after all — there’s no denying that she and I Am Number Four costar Alex Pettyfer are together…

The two castmates were all smiles at a recent event promoting I Am Number Four, and we can hardly handle how cute they look.  Do you think Dianna and Alex make a good couple?
