Miley Cyrus hat plaid shirt shorts juiceMiley's had to grow up fast as a mega-star in this business by just the age of seventeen, but is she ready to marry her boyfriend Liam Hemsworth of just 10 months?

A source tells OK that “She’s talking about a wedding as soon as she turns 18. She’s even asked her mom if she can wear her wedding dress.”

Although Miley's been known to move fast (her previous boyfriend Justin even moved in with her family!), she doesn't seem like the type to have her head in the clouds about these things.

In fact, future LOL co-star Demi Moore recently described the Hannah Montana star to MTV as "incredibly grounded."

Which is probably what Billy Ray is going to do if these rumors are true!

But at least she's got her freedom for now! Miley was spotted picking up some Robek's juice in LA yesterday afternoon wearing her hat down low around her eyes. And yes, that is a Phoebe Price original!
