The 24-year-old star took a photo of herself in the bath with her 20-month-old son, Astala, and when she checked the image she was shocked to discover a set of discoloured fingers by her shoulder, reported Femalefirst online.
Peaches lives in the property in Kent, South East England, with her husband Thomas Cohen, Astala, and their other son, eight-month-old Phaedra.
"The house was built in the 1920s by a rich man and his pregnant wife. However, his wife had a stillborn baby and was so grief-stricken she went mad. She apparently drowned herself in the bath," Peaches said.
Peaches has started to leave her door open when she sleeps at night in case the 'ghost comes back'.
