Today's hot girl is Mila Kunis. Mila is the birthday girl who turns 29 today. The last year she can call herself young. Haha I hope she rocks out hard and parties even harder. 30 is hard to grasp. Mila has become a big movie star and a sex icon ever since her days on That 70s show. Hopefully she keeps it sexy well into her 40s. Picture gallery of the hot birthday girl below.
