The singer-and-actress was reportedly delighted when she came across a dessert stand backstage at the Nickelodeon Kids` Choice Awards as it was stocked with her favourite type of sweet treat.
An onlooker told website HollywoodLife: "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.
"Miley was like, `You don`t understand, Sprinkles is my thing,` and said her mom `has a cupcake problem` too."
While attending the star-studded event in Los Angeles, Miley was quizzed on rumours she has reunited with former boyfriend Liam Hemsworth.
However, she shrugged off the questions, saying only: "Shhh! I`ll never tell. My lips are sealed."
The 18-year-old star is preparing to tour Liam`s native Australia and she can`t wait to get back on the road again.
She told US TV show `Extra`: "I love being on the road and travelling."
Miley and Liam, 21, split last August after around a year of dating, before reconciling the following month and eventually splitting again in November.
