The pop songstress uploaded a strange snap of herself wearing a set of large comedy teeth over the weekend, while cuddled up to one of her pet pooches.
But we don't think her dog is too impressed with the new look!
In the photo, Miley appears to be make-up free and she has also swept her short hair forward to resemble a slight fringe.
Perhaps she was bored?
She later tweeted: "why are people sooooo seriousoooo?", as if to explain her light-hearted reason for posing with the goofy teeth.
Also over the weekend, Miley spent some quality time at home with her pets and a large tub of ice-cream.
It sounds like the star was in a reflective mood too, as she admitted to feeling "emo" on Twitter and then wrote: "I love being alone on Sundays".
Last year, Miley and fiancé Liam Hemsworth broke off their engagement and the chart-topping singer has since been enjoying her single status by frequently partying with friends and focusing on her career.
And although she enjoyed wearing her impressive diamond engagement ring, Miley is much more fond of having down time on her own.
Last month she said: "It was so fun wearing a fat rock for a few years. But now, I just feel like I can actually be happy. I wait for those moments of silence, when I'm just at my house, by myself."
