Miley Cyrus VMAs 2013 Performance Ends Engagement With Liam Hemsworth? ‘Hunger Games’ Star Was ‘Mortified’ After Performance

Liam Hemsworth was mortified after his ex-fiancé Miley Cyrus' VMAs 2013 performance, RadarOnline.com reports, leaving many wondering if her show was the final straw in their relationship.

"Miley and Liam were already pretty much broken up at that point, but when he saw her performance and the backlash it created, it was the nail in the coffin," a source exclusively told Radar.

"That was all he needed to finally break up with Miley once and for all. He was embarrassed, disgusted and mortified by her performance."

Liam Hemsworth's sister-in-law Elsa Pataky urged him to break up with Miley Cyrus for over a year, Radar Online also reports.

Elsa, the wife of Liam's big brother, Chris Hemsworth, "is no fan of Miley," a source close to the Hemsworth family told the website.

"She spent the last year freezing Miley out in some kind of passive-agressive move."

"Elsa is totally against Miley and Liam getting back together. Miley desperately wants to get back with Liam and believes she can because she's done it before," the source insists. "But to do that, she's going to have to win over Elsa!"

Miley Cyrus was interviewed on the "Today" show on Monday and performed her hit single "We Can't Stop," showing off her twerking skills, leaving many wondering if she's already over her break up with Liam Hemsworth.

Liam Hemsworth's ex-fiancé told host Matt Lauer that she's the happiest she's been since her split and that she's doing a lot better.

But Miley Cyrus also hosted Saturday Night live last weekend and avoided making jokes about her ex-fiance Liam Hemsworth, leaving many fans wondering if she's still in love with the "Hunger Games" star.

"She thought it wouldn't be classy at the end of the day to talk about Liam and left him out it," a source told HollywoodLife.com
