I suddenly really feel the need for a cigarette…girl. Here are hot sisters, singers and actresses Aly and AJ Michalka at Kate Hudson’s Halloween party. AJ donned a Queen of Hearts costume and Aly chose to be a cigarette girl.The former Hellcat cheerleader Aly Michalka goes and dresses up in a cleavetastic little number for Halloween night, flashing just a teeny tiny nub of nipple. Check out her left breast. I admit I had my doubts that it was nothing more then wishful thinking until I looked a little closer. And yes, I can confirm that this is Aly Michalka nipple slip. The girls have posted some more pictures on their Twitter of them at Kate Hudson’s annual Halloween Party with some other celebrities, including friends Miley Cyrus, Emma Roberts and Zac Efron . Miley Cyrus opted for the best of both worlds, looking scary and sexy in a low cut top and an interesting variation on skeleton makeup that has been popular this year.Now you can enjoy.
