HELP MY FIND A VIDEO

First, ignore the gif , i just used it because theres no way to post without linking something here and I couldn't find anything from the video i was looking for. Maybe some of you guys know or have watched the video. In the video theres an actress that i think its Diamond Jackson or someone that looks like her, shes using white yoga pants i guess and she comes for her yoga class, but her instructor wasnt there that day so she had a substitute. Does anyone know this video?
