But recent pictures show Miley looking slimmer than ever - so all in all, we're a bit worried about her.

Miley has taken to Twitter several times over recent weeks to tell her followers how guilty she's felt after indulging her cravings.

She continued: "I now remember why I never eat pizza. It makes me feel like s**t. Ate to much pizza and French fries. Yoga and a swim in the a.m."

And following her fiance, Liam Hemsworth's birthday, she tweeted: "Back to raw tomorrow. Right after these birthday cake Oreos."

The singer and actress was dressed in tailored black trousers and a patterned jumper which looked like they were hanging off her.

And last week she tweeted a photo of herself trying on clothes in a shop, including a pair of shorts which showed off her tiny legs.

We hope Miley's OK. We have plenty of biscuits at ours if she wants to pig out.
