[#LadyGaga] U2 Show 10/7- Gaga?

This was 10/7 at the U2 show, about 2 hours prior to the start. We were on the rail and snapped these pics. We were just told it's Gaga… Can anyone confirm who's in these pics? Different outfit than she was spotted in that night but this group spent a while looking into the equipment and tech here at the stage.
