We suspected on Twitter that things weren't right between the couple...

Now it's been confirmed! The cute American couple have gone their separate ways...

The Disney star was dating Justin for a year after her dad introduced them to eachother. Miley's mysterious tweets started last week, check them out!

"I hope that I'm dreamin, cause I'm sick of this feeling."
"Tears are words the heart can't express"         
"why does saying good-bye hurt so much?"
"daddys giving me therapy. this is worth 10000000 dollars"
" i'm just to far from where you are, i wanna go home."
"trying to smile through a gloomy day in savannah."
"life will go on. you will smile again.... we will smile again."

It all makes sense now! They obviously split up some time ago but it's been made official now, a source said: "They have been having trouble for a while, it's been hard for a long time since Miley has been working so much and traveling a lot."

Here's Justin's tweets...

"All day staring at the ceiling making friends with shadows on my wall"
"Haven't been this miserable in a looong time.. I thought highschool was over"
"and in the end the love you take is equals to the love you make"
"I'm taking a twitter break for a while.. I love everyone.. Even the mean people.. Everything works out for the God's good"
"Sleep just can't find me tonight"
"I almost fell asleep.. I think I did for like 10 seconds.. Obviously it didn't work out"
"How many tears are in* there? They've gotta run out soon right?"

What do you think of the couple splitting up? Do you think Miley can do better than the model Justin?
