The images originate at the Daily Mail where it’s noted Adams is in-between takes.
Well, Adams is wearing her engagement ring in the photos leading to speculation that Lois Lane is engaged in Batman Vs. Superman.
A simple check of Google images brings up pics of Adams in public wearing the same ring.
She’s engaged (like for five + years) to Darren Le Gallo.
