After attending one semester of college between gigs, she realized that she wanted to act for the rest of her life. She started acting when she was just 9-years-old, when her father heard about an acting class on the radio and decided to enroll Mila in it. There, she met her future agent. Her first gig was in 1995, in which she played a character named Melinda in “Make a Wish, Molly” (1995).

From there, her career skyrocketed into big-budget films. Although she is mostly known for playing Jackie Burkhart in "That '70s Show" (1998), she has shown the world that she can do so much more. Her breakthrough film was “Forgetting Sarah Marshall” (2008), in which she played a free-spirited character named Rachel Jensen.
