Dianna talking about filming with Lea and Faberry friendship at Giffoni Festival in 2012.
Lea talking about playing Quinn on Glee and dressing up as Quinn for Halloween at Giffoni Festival 2014.
Mentioning Dianna isn’t a PR move IMO. She just talked about being dressed up as Quinn and we know that at this party she hung out a lot with Dianna so that’s probably the first name that popped up into her head? I don’t know she mentions Quinn just like she did in 2011 I think so that’s not a surprising answer. And it reminded her of that party that’s all. As for Matthew my opinion is here.
