Miley Cyrus has a hippo onesie that her lover Liam Hemsworth finds ''sexy''.

The 'We Can't Stop' singer wears the animal pyjama suit when she is relaxing at home and when she puts it on she can't stop eating - just like the marble munching 'Hungry Hungry Hippos' in the children's tabletop game of the same name.

She revealed: ''I have a hippo (onesie), which my boyfriend thinks is really sexy. So when I come downstairs it's Hungry Hungry Hippo and I just go and smash everything and eat everything in sight.''

When Miley isn't dressing like a hippo, she likes to experiment with her fashion choices.

The 20-year-old star - who got engaged to Liam, 23, in 2012 - has completely changed her look from her days playing 'Hannah Montana' and she gets a lot of clothes from ''bondage stores''.

Speaking to MTV, Miley - who also chopped her brunette locks into a peroxide blonde pixie crop - revealed: ''You can just mix white trash and Chanel, that's me. That's my ultimate look.

''Pretty much everything is from weird bondage stores except obviously my jewellery - gotta keep it classy with Chanel. I wear a lot of jewellery during the day, so I pretty much just come with my own jewellery, and give me some underwear to wear with it, and I call it a day.''
