The actor is believed to be increasingly frustrated at Miley's insistence of writing every single feeling she has immediately online for all to see.
Just this weekend a rather melodramatic sounding Miley wrote: "Why do I torture myself and what ps I love you. ahhhhhh. I have got to pull it together."

She also retweeted: " Twitter followers, red carpets, awards, "success" none of that is real."
However, we get the feeling Liam regards those followers as slightly more 'real' than Miley does, and it would seem it is driving him mad!
A source told Star: "Miley's tweet was such a huge insult to Liam. She tried to pass it off like it had nothing to do with him, but it totally affected him, no matter what she tries to say."
"She was trying to get his attention, but she just ended up making him pull away from her more."
Miley has around nine million followers so it's understandable why Liam might be feeling just a teensy bit exposed.
Liam himself has never had a Twitter account and in 2009, convinced Mley to close hers too when she tweeted: "FYI Liam doesn't have a Twitter and he wants ME to delete mine with good reason."
However, a few months later she was back and her emotional tweets have been flooding our timeline ever since.
Maybe Liam should just buy Miley a diary and a nice fountain pen for Christmas, eh?
