Former Disney starlet Miley Cyrus called into Ryan Seacrest's KIIS FM radio show this morning (October 18) and spoke about her relationship with actor Liam Hemsworth, on-screen love scenes and the new song by Jonas Brothers.

She explained that when new scripts are presented to them, they have a mutual understanding of what would be inappropriate to write about in a song or portray on-screen as an actor and use that to measure which roles to accept or how to create new music:

"It's like at this point we're engaged, we're forever. I think if I was a girlfriend and all this stuff would happen I'd feel more hurt and would need to show my ownership... the thing is we really do care about each other and what we think, so I've turned down scripts because I've felt like it was things that not only make me feel uncomfortable - I don't think any career is worth stressing out the person you love the most."

Seacrest then mentioned a new song from the Jonas Brothers that was debuted recently, entitled 'Wedding Bells', and asked if Cyrus had heard it because it's supposedly about her past relationship with Nick Jonas and she explained:

"I don't know who else is getting married so I feel like that's pretty blatant... but, you know, it's... whatever. Everyone has to write songs that are about things that they felt and even he introduced that as it isn't the way that I am and this is just something... 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 or someone who's a writer."
