A performance artist who said giving birth is the "highest form of art" has delivered a baby boy – in a New York art gallery.
The Microscope Gallery in Brooklyn said Marni Kotak gave birth to a healthy infant, weighing 9lb 2oz.
Kotak, 36, had set up a home-birth centre at the gallery, turning the space into a brightly decorated bedroom with ocean-blue walls. She gave birth in an inflatable pool.
The gallery said in a statement that "Baby X" was born on Tuesday morning and that a video of the birth will be added to a forthcoming exhibition.
