Karolina Kurkova celebrated her 28th birthday with a high-end fashionable pajama party in LA. The supermodel and her close pals, including Rachel Zoe and Montana Coady, got together for the relaxed celebration at a private residence after the Oscars. A source told us, “After all the Oscar parties, the dresses and the red carpets, Karolina wanted to do something relaxed and fun to celebrate her birthday. Rachel suggested a pajama party. It was a really lovely, cute event.” Statuesque Victoria’s Secret beauty Kurkova was ready for a quiet night in after gracing awards bashes including the Weinstein pre-party Saturday and Madonna and Guy Oseary’s post-show party.
