It appears someone has too much time on their hands.
Miley Cyrus has tweeted yet another picture of herself and her ultra miniature waist.
The Hannah Montana actress was clearly so impressed with her own figure, that she even chopped off her head from the snapshot to focus solely on her taut and toned midriff.
Alongside the picture, the 19-year-old added the caption: 'my "Fiance" jeans. but for real though.'
Too much time on her hands: Miley Cyrus posts yet another show-off picture of herself in which she flaunts her flat stomach, alongside the comment: 'my "Fiance" jeans. but for real though.'
The wording is a play on the popular boyfriend-style of jeans that are popular with girls who favour baggier trousers and the fact that Miley is now engaged to Hunger Games star Liam Hemsworth.
Following the former Disney princess' obsession with Pilates and workouts, it seems her figure has continued to shrink, with Miley taunting critics by flaunting her sculpted body at every opportunity.
Even her fitness instructor spoke out on the issue, but in Miley's defense saying there is nothing to worry about when it comes to the Party In The USA singer's health.
Mari Winsor told People: 'I think people need to chill out. She's healthy and she feels good, that's the main thing. She's smart about her body. She wanted to sculpt her body, that's all.'

The fitness guru added: 'When this girl comes in, she is on fire. She's focused.'
But whatever Miley's secret, it seems she may not be so sure herself - or at least, doesn't want anyone to know.
Back in April, she claimed her changing shape was not a quest for size zero, but a health issue.
Cyrus tweeted: 'For everyone calling me anorexic I have a gluten and lactose allergy. It's not about weight, it's about health.'
However, last night she insists she does eat, saying: 'upallnighteatinchicken&waffles/makin beats'.
