Miley Cyrus 'No Support' from Liam Hemsworth and Family for Racy VMAs Performance [VIDEO]: 'We Can't Stop' Starlet Didn't Want Fiance Witnessing 'Over the Top' Twerking

Miley Cyrus' controversial "Blurred Lines" performance at the 2013 VMAs is STILL going viral. Everyone's talking about the 20-year-old songstress' raunchy twerking skills - but what does "Hunger Games" fiance Liam Hemsworth think? He didn't even attend the awards show... and apparently Cyrus didn't want him to! Read on for more deets.

According to a Hollywood Life "insider," Cyrus is all about promoting her music career. And that's what Sunday evening's racy performance was all about... just another day at work for the former "Hannah Montana" starlet. Therefore, her more laidback fiance had no reason to witness her "over the top" show.

"Miley knew her performance was going to be outside his comfort zone and she didn't want to be worrying about him in the audience and how he was going to react," the source explains. "The whole thing was just another day of work for her, she wants her album to be number one and that means promoting the hell out of it."

But what about Hemsworth's family... are they supportive of Cyrus shaking her booty all over Robin Thicke?

"Liam's family is very conservative, so she knows they won't approve of her performance," the source continues. "But she had to make a decision when she started all of this, is she going to shape her career to please Liam and his family? Or is she going to be the artist she wants to be?"

The Hollywood Life insider finishes off with, "She loves Liam and she wants to make him happy but it does seem pretty clear that her own career is the most important thing to her right now and what's wrong with that? Liam is putting his career first, no one is expecting Liam to pick his movie roles based on what will make Miley and her family happy. So why should she base her career on what will make him and his family happy? It's not something she can worry about or it will drive her crazy."

This alleged "source" such does have a lot to say about the matter... what do Mstars fans think?

Apparently, Cyrus and Hemsworth's relationship is still going strong!
