Miley Cyrus is convinced the new JONAS BROTHERS song Wedding Bells is all about her.

The pop star and actress, who became engaged to wed Australian actor Liam Hemsworth earlier this year (12), once dated Nick Jonas, and though she's more than a little upset with him for not giving her any warning he had written a tune about her, she accepts songwriters often pour their emotions and experiences into their work.

During an appearance on Los Angeles DJ Ryan Seacrest's show on Thursday (18Oct12), Cyrus was asked if she thought the tune was about her relationship with Jonas and she shot back, "I don't know who else is getting married... so I feel like that's pretty blatant."

But she insists she doesn't plan to make a big deal of the drama: "Everyone has to write songs that are about things that they felt... so you can't ever hate on someone for writing about something you've been through. I think that you kind of get a fair warning when you date an artist and someone that's a writer. When you're going through things, you're going to end up hearing about it on the radio."
