It looks like 'Gypsy' is the next single from popstar Lady Gaga's current long player, 'ARTPOP'.
According to this here website that collects together new songs being added to radio in America, 'Gypsy' will follow 'Do What U Want' as the next 'proper' single.
It's also been added to this Interscope Soundcloud playlist of news songs to be promoted too, so it seems likely.
Fingers crossed this one will have a video. Set your alarms for 2016!
