Dianna Agron - Likes Girls Shirt - Glee Live Tour

During the Born This Way number at tonight's show, Dianna Agron sported a Likes Girls shirt instead of her usual Lucy Caboosey shirt. Did she just misplace her usual shirt? Is she trying to tell fans something or just having fun? Is this a new development for her character?

Personally, I'm not making a big deal out of it but fans of the show can't stop talking about it so I thought It warranted a post. This makes me like her more actually.
