Please help me find this performance

The lead singer was wearing black shirt, bluish baggy sweatpants, with darker back pockets. She had black hair, and during the short she props her leg on a chair during a stage, cameraman zooms on her from behind, and she taps her leg to redirect him up. Pink and blue stage lighting. Comments were loving her. I wanted to find out what the song was and who it was by but I forgot the name of the group, can anyone help?
