"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," said a source.

"He thinks she's acting like an immature schoolgirl, and he wants her to get off Twitter completely," the source added.
