US Congresswoman Mary Bono Mack had already given a very moving tribute to stepson Chaz Bono at the GLAAD Media Awards in Los Angeles on Saturday (21 April).

She talked about how Chaz 'meant the world' to his dad, the late Sonny Bono, who she said was 'watching from heaven.'

'Chaz had the courage to follow his heart and his convictions and that's what true leaders do,' Bono Mack said.

Then, after a video presentation about Chaz, a woman wearing a dramatic afro wig  a wig came onto the stage unannounced.
