To the surprise of probably no one, Miley Cyrus rides the immense popularity of her "Wrecking Ball" single to her first No. 1 on the Billboard Hot 100, leaping from No. 22 to the top spot in just one week and knocking Katy Perry's "Roar" off the perch.

Cyrus' previous career high on the chart was No. 2 with this summer's "We Can't Stop" and 2009's "Party in the U.S.A."

More than 19.3 million viewers watched the provocative "Wrecking Ball" video when it debuted on September 9, and its continuing appeal has helped it sell more than 477,000 downloads, another career high for Cyrus.

This week's showing also makes her the first member of her family -- including father Billy Ray Cyrus and brother Trace with is band Metro Station -- to hit No. 1.

In related "Wrecking Ball" news, Grand Valley State University in Allendale, Mich., has been forced to remove a steel ball pendulum statue on its campus because students have been reenacting the "Wrecking Ball" video and posting tributes online.

A university official commented that, "We've been reviewing this over the last couple of weeks, trying to decide whether we really need to look at the structural integrity of the installation. We decided to have the ball removed and put into storage for now."
