For a 20-year-old, Miley Cyrus sure has a potty mouth. She cusses up a storm in her March 2013 Cosmo cover, where, we might add, she looks bangin' in a blazer with no bra and white blonde hair.

Miley is as confident as her haircut in the accompanying interview. She pretty much throws that Hannah Montana broad under the bus, though. But she also referred to actor Liam Hemsworth as her hubby. Wait ... did she just out herself?

Here's some of what she dished about.

Her top priority? That hot Aussie fiancé of hers, Liam Hemsworth. "That's what I feel the most confident in because you never know; there's so much hype behind my new record, but it could come out and, worst-case scenario, everyone f---ing hates it." She often sneaks a peek at her man and thinks, "'You are hot, dear god!' The other day, I turned on the pool heater and it was steaming, and he walked outside and took off his clothes and jumped in the pool. I was like, 'I'm gonna faint -- the hottest guy of my life is in a steaming pool. This looks like a Playgirl shoot.' So I took a photo and made it the background on my phone. My best friend grabbed my phone and was like, 'Who's that? He is so hot!' That's my hubby!"

Wait, she said hubby! He's not her hubby yet ... did they get married in secret? Or is she just practicing referring to her man as such?

On being free of Hannah Montana, professionally: "I've never gotten to make a record like this because Disney's always been on my back saying, 'You've got to promote the TV show in two months, so make sure your record's done ... and when you promote your record, can you promote the show, the movie, and the 'Hannah Montana' record?' I was basically carrying two people's careers and trying to make mine the priority. Now, it's almost like being a new artist and trying to make a first impression. I think the best thing I could have done was take those two years off to really live, because now people don't think of me as who I was on the TV show."

Who she's not trying to be: "I wrote this song with Mary J. Blige, and Tyler, the Creator heard it and said, 'I am obsessed with this song, and I will guest on it if you promise me that you will keep it on the album.' And he killed it! I really didn't want to make a hip-hop record, and I'm not trying at all to be a Rihanna or a Nicki [Minaj]....That's not my vibe. When I was growing up, my older brother would sneak me Nelly CDs, my dad had me listening to Dolly [Parton] and Johnny [Cash], and my mom is a complete metal head. So this record is a weird mixture of all that."

Which pop starlet has been her friend for "f---ing five years?" Katy Perry! "I'm not ever gonna let our work get between that relationship. If Katy sticks with being Katy, and Kesha is Kesha, and Rihanna is Rihanna, and I'm me, there's room for everybody. The problem is when people look at Gaga and say, "Oh, that works; I'm going to be like that.'"

We're still stuck on her calling Hemsworth "hubby..."
