Hayden Panettiere - Panettiere's Kooky 21St Birthday

HAYDEN PANETTIERE celebrated her 21st birthday with a kooky party filled with burlesque dancers, fire-breathers and performers dressed as CHARLIE AND THE CHOCOLATE FACTORY-style Oompa-Loompas.

The Heroes actress reached the landmark age on Saturday (21Aug10) and was treated to a quirky bash, organised by her Scream 4 co-star David Arquette who hired out the four-storey Cavern Club venue in Ann Arbor, Michigan.

The actor filled the party with performers from Vaudeville-inspired comedy show Beacher's Madhouse and presented the star with a specially designed 3D dolphin cake, to celebrate Panettiere's love of the sea creatures, according to TMZ.com.
