Miley Cyrus has to hit the gym, but first she set the record straight...

The blonde bombshell tweeted a pic of her new outfit - a mint green sweater and shorts that showed off her slim figure - and decided to celebrate her fashion victory like most 20-year-olds: with some pizza!

But things went a little awry when Miley tweeted a play-by-play of her evening, inciting a food fiasco: 

"Tooooo. Muuuuch. Pizzzzzza. back on the health train tomorrow. #cheatnight. You cant always control what goes on outside. But you can always control what goes on inside. I now remember why I never eat pizza. It makes me feel like shit. #glutenized"

That series of tweets must have upset the weight gods, because Miley quickly clarified her comments and explained what she meant when she said she felt like shit.

"Let me clarify "shit" wasn't meaning "fat" I mean sick. Because gluten is poisoning me. Your stomach has a brain too & it hates SHIT food." Later she added, "Ate to much pizza and French fries. Yoga and a swim in the a.m."

It's long been reported that Miley is on a gluten free diet - and according to her new figure and clear skin, it's working for her. We'll still take the pizza though!
