The 30 Hottest Actresses Under 30

We've already established that age ain't nothing but a number to us here at Complex with our list of the 40 hottest actresses in their 40s. Now we're showing you the view from the younger side of Hollywood, a crop of both up-and-coming and established ladies who have come to take up the mantle from their elder stateswomen: the super-heroine, the girl next door, the unattainable love interest.

One of the leaders of the rising new class of actresses, Mila Kunis, is entering the final year of her 20s today, so in honor of her birthday we give you The 30 Hottest Actresses Under 30.
