Happy 17th Birthday, Miley Cyrus!

The actress had a throwback 17th birthday bash before the tragic incident with her tour bus...See her celebrate

Before her tour bus's tragic crash, it was a Party in the USA for Miley Cyrus' 17th birthday.

More like party in the Big Apple, actually.

The teen queen (who's actual birthday is today), was surprised by her mom with an '80s rocker themed bash at the Canal Room last Wednesday, with about 200 friends, her tour crew and dancers attending. 

Big brother Trace and boyfriend Liam Hemsworth were also on hand for the throwback fete, featuring performances from the Rock of Ages cast and a special cake designed by TLC's Cake Boss, Buddy Valastro.

Liam and Miles couldn't hide their affection during the bash...

"She and Liam are definitely a couple," an insider tells E! News. "They were holding hands, canoodling and looked like they were really into each other."

There was no boozing because of the underage B-day girl, natch, but party goers like Shannon Elizabeth and Derek Hough dined on comfort food like mac and cheese, mini pizzas, sliders, chicken fingers and Miley’s favorite, sushi, all provided by Cocktail Caterers.

Of course, in true Miley fashion, the fete wasn't without some controversy.

Some bloggers slammed the birthday girl over her provocative outfit, which was a belly-baring shirt, tiny shorts and high boots.

We really wouldn't expect anything less from her.
