LOS ANGELS: Miley Cyrus will celebrate turning 17 next month (Nov09) with a Dolly Parton-themed birthday bash.

The singer hails from the same Nashville, Tennessee hometown as the buxom country queen - and admits Parton's one of her idols.

So she's preparing to boost her bust and slip on a big blonde wig for a party on 23 November - and she's insisting all her guests dress as Dolly too.

During an appearance on U.S. presenter Ryan Seacrest's radio show on Friday (30Oct09), Cyrus told the host, "I want to rent out a cool place and play all Dolly Parton music and have everyone dress up as their favourite Dolly moment.

"I am really excited about getting all my crew members to dress up as Dolly. That's probably going to be the funniest thing ever."
