Adele has reportedly spent thousands of pounds on two rare butterfly canvases by the pop artist for the living room.
"Adele and her partner Simon Konecki had the pair of prints delivered to their house in the past month.
"The Warhols have already been hung in pride of place on the walls of the living room at the huge house. Adele has been kitting out the place now they are back from LA with baby Angelo," a source said.
