On Monday we wished Cara Delevingne a happy 21st birthday and rounded up the highlights from what has shaped up to be a phenomenal year for the British supermodel. Now the blonde star has revealed a glimpse of how she celebrated her milestone birthday and true to form it involved loads of mates, experimenting with fancy dress and pulling a funny face or two to boot.

In an undisclosed location the group of revelers, which included sisters Lizzie and Georgia May Jagger, channeled Cara’s cross-dressing party theme in a selection of sparkly leotards, colourful wigs and fake moustaches. The birthday girl herself wore stars and stripes leggings, a black crop top and a sparkly hooded cloak while Lizzie showed off her figure in a skintight harlequin onesie. In one photo a male friend is seen posing in a dress with slicked back hair.

Unsurprisingly the ever-popular Cara was showered with gifts and posted an image of her pressies wrapped up before she opened them with the caption, “I am so lucky!!” She also shared a special message of appreciation with her pals after the event on Instagram: “Thank you to all my friends for all their love and support and for making my birthday so special, I would be nothing without you! #crossdressing #sparkles #camo #itsbeenemotional.”

Meanwhile Miranda Kerr has revealed images from the forthcoming Pirelli 2014 calendar in which she stars alongside fellow supermodels Helena Christensen, Alek Wek, Isabeli Fontana, Karolina Kurkova and Alessandra Ambrosio. This years edition, which will be released in November, commemorates the 50th anniversary of the Pirelli calendar and was shot by esteemed photographers Patrick Demarchelier and Peter Lindbergh in New York.
