Miley Cyrus 'Gets Musical Birthday Surprise'

Miley Cyrus had one birthday party she'll never forget - the singer's mom booked her the cast of a Broadway musical as entertainers.

Smiley Miley turned 17 today (November 23) but celebrated last week with a huge bash at the Canal Room in New York, attended by family and friends.

And the party - which had an 1980s theme - was made even more special when the cast of 'Rock Of Ages' performed for the 'Hannah Montana' star.

On eyewitness told the New York Post: "Miley had seen the show two weeks ago and loved it, so her mom Tish brought the cast in to surprise her."

Miley's rumored boyfriend, Australian actor Liam Hemsworth - who is Cyrus' co-star in forthcoming movie 'The Last Song' - was also at the party.
