Lady Gaga has taken a swipe at critics who do not believe she is really bisexual.

While in Berlin to promote her upcoming third studio album ARTPOP, Lady Gaga put in an appearance at the famous Berghain Club.

Lady Gaga pursed her mustachioed lips for reporters while wearing leather underwear and a fur coat.

“You know it's not a lie that I'm bisexual and that I like women. And anyone that wants to twist this into, 'She says she's bisexual for marketing' – this is a fucking lie. This is who I am and who I have always been,” Lady Gaga said during a Q&A. (The video is embedded on this page. Visit our video library for more videos.)

ARTPOP arrives November 11.
