Miley Cyrus, Liam Hemsworth News Update 2013: Break Up Caused By Ignored Cell Phone Calls? ‘Hunger Games’ Star Shuts Off Phone After Argument

Miley Cyrus and Liam Hemsworth are arguing over her recent behavior but the "Hunger Games" star reportedly shuts off his cell phone after the couple fights, a source tells Hollywood Life.

"That's so hard on her," the source explains.

"It really, really upsets her when she can't reach Liam. She wonders where he's at and who he's with. It's torture for her, and it's her mom and dad that are left dealing with it."

Miley Cyrus' feud with Liam Hemsworth has also gotten her father, Billy Ray Cyrus, upset with the couple.

Miley Cyrus runs to her parents after every fight she has with Liam Hemsworth - and, obviously, they side with their little girl, Hollywood Life reports.

"It breaks Billy Ray's heart to see his little girl crying, and he blames Liam," the insider adds.

"Miley is still Billy Ray's baby, she always will be, so anytime someone hurts her he gets really defensive. Over the past few months, all the drama with Liam has been a huge emotional rollercoaster for her."

Liam Hemsworth is rumored to be upset at Miley Cyrus over her recent sexualized behavior.

Miley Cyrus wore a Julia Roberts' famous hooker dress from the iconic 1990 movie "Pretty Woman" at a music festival in Miami on Saturday and Liam Hemsworth might have gotten upset at her, according to Perez Hilton.

"They've had a lot of fights about it ... Miley doesn't think Liam has any right to tell her to tone it down. He plays different characters for his career and this is the character she's playing right now for her career," an insider told Perez Hilton.
