The main focus of this artwork is a nude sculpture of Lady Gaga. In the background, you can see shards of Botticelli's original work alternating with shards of a marble statue, which is Bernini's 'Apollo and Daphne'.
Between Gaga's legs is a large blue metallic pearl. There's a reflection in the pearl that is presumably the studio in which this work was created.
Love it or hate it, Lady Gaga takes her art very seriously. The album artwork represents her giving birth to art.
The artist behind this cover (Jeff Koons) explained Gaga as Venus in this way:
"And also in this triangular shapes that go out is Botticelli's 'The Birth of Venus,' presenting Gaga of course in the role of Venus — of the nature of the continuation of life's energy and the pursuit and the enjoyment of aesthetics and of beauty. And of the desire to continually have transcendence."
