Last night/this morning (22-23/11) Miley celebrated her 22nd birthday at Factory nightclub in Los Angeles. All of her friends were there to honour Miley. Her party was themed "Miley's Happyland" and included inflatable animals and sex dolls, all kinds of sparkling and colourful decorations, balloons and a giant cake in the shape of a pizza.
