Click through to see a timeline of their rocky relationship, then let us know in the comments below if you think they've broken up a few too many times. Brenda and Trace first went public with their relationship in May 2010 at Nylon Magazine's Young Hollywood Party.
Prior to their relationship, Trace was linked to Demi Lovato in June 2009 and Brenda dated Joe Jonas in August 2009.
"I apologize for not clearing this up sooner and for the continual defame that these lies have caused @Trace Cyrus.
He's just the same as everyone else," one commenter wrote.
A second added: "Why the hell." Song and the Metro Station rocker, 26, called off their engagement in 2012 after over a year of dating. We will continue to focus on our careers," Cyrus told Us Weekly in a statement that June.
“A few years ago there were rumors that I was pregnant and/or had a miscarriage.
I just want to say that those rumors were not true. I apologize for not clearing this up sooner and for the continual damage that these lies have caused @Trace Cyrus.” The post was deleted quickly at the time, but not quick enough before Cyrus opened up about it directly on Song’s Instagram.
