Citing “sources close to the studio”, French website ActuGaming claims the singer has recently been in and out of the Cyberpunk 2077 developer’s offices in Warsaw, Poland. The Google translation of the article is super awkward, but explains that “from what we know, the artist would have gone to CD Projekt Red to potentially perform a performance in motion-capture”.
This speculation is backed up (kind of?) by this otherwise inscrutable response by the game’s Twitter account to one of Lady Gaga tweets from 2012, implying some sort of collaboration between them.
