Stunner Mila Kunis, star of “That ’70s Show” and Darren Aronofsky’s Black Swan, is now officially a MILF. She’s been a hot mom for years, but her petite frame and youthful good looks—and seemingly stress-free kids—have kept mommy roles away from the tiny bombshell, with the Bad Moms franchise being the notable exception.

At the ripe age of 42, Kunis is playing a milf in Don’t Move directors Adam Schindler and Brian Netto’s Nightwatching, produced by Ridley Scott. Adapted from Tracy Sierra’s page-turner of the same name, the thriller stars Kunis as a hot milf trying to keep her kids safe during a home invasion, fearful of who’s behind it and why.

Kunis made her feature film and horror debut at age 12 in 1995’s TV remake of the 1978 Joe Dante film Piranha. She followed that up as a legal teen with the lead in much maligned American Psycho 2. Success and acclaim came with roles in the Hughes Brothers post-apocalyptic actioner The Book of Eli and Aronofsky’s Oscar-nominated Black Swan—showcased as the top pick in Clatto’s esteemed list of The 10 Sexiest Horror Films of 2010.
