Miley Cyrus' Wrecking Ball a plea to Liam?

Wrecking Ball is the latest video from Twerk queen Miley Cyrus, an emotional plea to a lover that she still loves him, while Cyrus licks a sledgehammer and rides a wrecking ball without any clothing.

But the tears generated amidst all the sexual posturing is what has people talking. Some say that those on set were most shocked by the tears coming out of Miley's eyes.

Even though Miley Cyrus was reportedly happy and in a good mood, "it only took like two seconds for her to start crying," an insider tells Hollywood Life.

"When [director Terry Richardson] wanted her cry, he told her to think about losing Liam and boom, she went from happy to breaking down."

The source adds that the shoot "wasn't an act" and that the "song is obviously very personal for her."

Cyrus and Liam Hemsworth are reported to be breaking up.

Cyrus also was struck from Anna Wintour's list of celebs to flaunt on the cover of Vogue.
