Amid rumors of relationship troubles, Miley Cyrus admits that she and fiance Liam Hemsworth lead busy, separate lives.

"I'm not home with my boyfriend all the time. We work. Every week it's 'Are they broken up? Because we don't see a photo of them,'" she told V magazine's May issue.

"I don't have time go to Starbucks with my boyfriend every morning. I wish I did, but I don't," she continued. "I'd rather chill at my house and be there for the time I actually get to spend with him. And then I'm at the studio all day. He gets up to work out at six and I come home at five from the studio."

Cyrus, 20, has been hard at work on her latest album with producer Pharrell Williams.

"I put this record before everything, and I've never done that with anything. I've put too much into this record to put anything else in front of it," "The Climb" singer and former Disney star told the magazine.

The new album is a departure for Cyrus.

"I can never say that I don't love 'Party in the U.S.A.' and that I'm not appreciative of it. It would be like my dad saying that he hated 'Achy Breaky,' Cyrus said, referring to her father Billy Ray Cyrus. "It's what gives you everything that you have. I would never take it back."

But Cyrus is also unafraid to change.

"I'm going to change, I'm going to be different, I'm going to do what I want to do. I chopped my hair and bought a pair of Docs and never looked back," she said.

While she and Australian actor Hemsworth, 23, have been engaged since last June, even Cyrus' father is uncertain if they'll wed.

"They're young, they're kids. The great news is they're great friends. They're really, really good friends," he told ABC News' " Nightline" recently. "I play it by ear, and I know whatever is meant to be, that's the way it's going to happen."
