Miley Cyrus may have just dropped a hint as to why things aren't going so well with fiancé Liam Hemsworth.

During a Google Plus live chat on Tuesday with will.i.am, the 20-year-old "Party in the U.S.A." singer revealed just how hard she has been working on her upcoming album.

"I am so excited, all I do is focus on my music," Cyrus said. "The only place I ever am is at the studio. My friends, my relationships with everyone around me have honestly changed since I've been working on my record, because it's the only thing I have wanted to give 120% to."

Continued Cyrus: "I think it's, like, the only time in my life that I have pushed everything aside, everyone aside -- anything that really mattered, and it just became about the music."

According to will.i.am, Cyrus's effort shows: the Black Eyed Peas singer could not stop raving about how awesome her new music is.

So, where does that leave the "Ashtrays & Heartbreaks" singer and her "Hunger Games " beau?

Cyrus was once again photographed over the weekend without her engagement ring (although it was back on by Monday), and both People and Us Weekly are reporting her wedding to Hemsworth is not going to happen.

Here's how one source puts it to omg!: "They have a very up-and-down, young relationship. No one can keep up anymore." Another source says Hemsworth and Cyrus are "still together," just "not actively planning their wedding."
