Regarding the Nicki audio, it’s originally from an interview given to a french channel by ballet dancer Jonathan Klein, who took part in a french talent show competition around 2012. You can find the video the audio was taken from here: https://you tu.be/Rwl21dY2934
[And it was paired with an image that appears to be of model Tomek Szczukiecki][so maybe it’s him?]
Sorry to tell ya that I DON’T KNOW WHO THE AUDIO IS FROM ;A; AND THE ORIGINAL POST DIDN’T TAG HIM, EITHER. @devilsviolinist was the original poster and I’m not sure if that mun is active… try asking them and report back if you find out.
