Mila Kunis was looking adorable in a Styrofoam crown as she celebrates her birthday yesterday. Anyone else would look ridiculous but on Mila its just cute – it helps to be devastatingly beautiful, of course. Mila celebrated with many loved ones, including her long time boyfriend Macaulay Culkin and her friend Sarah Michelle Prinze, as well as her family. The party went on at Carlitos Gardel Argentinean Restaurant in West Hollywood, California. Mila was smiling as she walked around, kissing and hugging her family as they took breaks between meals.
