Miley Cyrus announces collaboration with Mark Ronson, seems to hint new song will be about heartbreak

Heartbreak alert!

Miley Cyrus is preparing to release new music and all signs point to heartbreak being a key theme of the new track, dropping on Thursday.

The singer took to social media on Monday to share a string-heavy snippet of the song along, along with a broken heart emoji.

“Miley was so excited to share a preview of her music,” a source tells ET. “Miley’s new sound is something a little more organic. She loved the pop, but she went for a more mature sound and sophistication in her new music.”

"Miley has always been great at reinventing herself,” adds the source. “She feels at the top of her game.”

The track is reportedly called, “Nothing Breaks Like a Heart,” and Cyrus’ latest Instagram posts have gradually spelled out the title on her profile page.

The singer’s first teaser played with a video of a giant, red disco ball-style heart rotating, split in two. “11/29  @MarkRonson,” Cyrus captioned the clip, tagging producer Mark Ronson, who she seems to have collaborated with on the track.
