The 18-year-old likes to indulge every now and again.
And backstage at the Nickelodeon Kids' Choice Awards on Saturday, Cyrus couldn't resist giving into one of her favourite vices.
A source told Hollywoodlife.com: 'Miley was with her publicist and told her to hang on for a second so she could come over to the Sprinkles cupcakes area and get a mini strawberry and a mini red velvet cupcake.'
The source added: 'Miley was like, 'You don't understand, Sprinkles is my thing' and said her mum 'has a cupcake problem' too.'
