Cyrus' ex Nick Jonas recently confessed his new song "Wedding Bells" is all about her. The pop star became engaged to wed Australian actor Liam Hemsworth earlier this year.
Some of the lyrics include: No, I don't wanna love if it's not you/ I don't wanna hear the wedding bells prove/
That we can't try one last time/ But I don't wanna hear the wedding bells chime.
