The 26-year-old former X Factor winner and vegetarian said that when she spotted the cute creature with a homeless man in Los Angeles, she had to do something.
'I felt so sad for both of them,' she told The Guardian.
'She was about this big (circles fingers), she would've died' she explained, adding that she offered him $20 to let her take the rabbit home.
'But he wouldn't take it so I gave him a hundred dollars. He saw me coming a mile off, probably does it all the time! But I love her soooo much.'
