Lady Gaga has insisted she was bisexual while promoting her new album ARTPOP in Berlin.
The 27-year-old singer turned heads as she promoted the album at Berlin's famous Berghain club, wearing a fake moustache and leather underwear.
Later, during a question and answer session with fans, the singer insisted she really was bisexual and not saying it as a publicity stunt.
"You know what it's not a lie that I am bisexual and I like women, and anyone that wants to twist this into 'she says she's bisexual for marketing', this is a f***ing lie, this is who I am and who I have always been," she said.
The singer is currently on a European promotional tour for the album.
