Miley Cyrus isn't even 18 yet, but that hasn't stopped her from planning a wedding with her boyfriend and Last Song co-star Liam Hemsworth.

Miley has already announced that she's no longer playing the Hannah Montana character, and she plans to move out of her parent's home once she turns 18. Now OK! Magazine is reporting that she is hoping to be wed soon after her birthday. She's known Hemworth for ten months.

"She's convinced she’ll spend the rest of her life with him... 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," says a source.
