The pop trio - consisting of siblings Joe Jonas, Nick Jonas, and Kevin Jonas - recently released a track from their new album titled 'Wedding Bells'.
Cyrus, who is now engaged to Hunger Games star Liam Hemsworth, dated Nick Jonas during her time as a Disney star.
During an appearance on Ryan Seacrest's KIIS-FM radio show on Thursday (October 18), Cyrus was asked if she believed the new track was about her.
She replied: "I don't know who else is getting married... so I feel like that's pretty blatant."
Cyrus added that she has no hard feelings against Jonas in regards to the song.
"Everyone has to write songs that are about things that they felt," the 19-year-old admitted. "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."
The Jonas Brothers' upcoming fifth studio album is due for a possible 2013 release.
