Out with the old and in with the, well, classic -- and at least temporarily.

Mila Kunis debuted a drastic new hairstyle this week at a private screening for "Bad Moms," ditching her long dark hair in favor of a shorter 'do that looks straight out of the Great Gatsby era.

The actress rocked a bob-length new style that featured tight wavy locks, perfectly accentuating her face. Her brilliantly done makeup only help highlight the hair.

However, Us Weekly states that it doesn't look like she actually cut her hair, but rather this was a case of "clever styling."

Her hair, the mag said, had been rolled and pinned into the nape of her neck, creating a faux bob.

Aside from the new faux 'do, Mila rocked a an embroidered Ulla Johnson jumpsuit with light pink pumps for the premiere.

Last month, Mila and her husband, Ashton Kutcher, announced that they are expecting their second child.

A few months prior to that, she told ET, "I'm not pregnant, but absolutely, I do want to have more kids one day, for sure."

She certainly got her wish. Now, though, she's gotta get ready for the unexpected again.

While promoting her new film in April, Mila said her and Ashton's 21-month-old daughter, Wyatt, is "crazy."

"Kids are crazy," she told an audience at CinemaCon while standing on a stage. "I don't really understand how they're all alive."

"Prior to human acknowledgment of 'Hey, let me keep my child safe, if [Wyatt] was here, she would just walk off the ledge," she said. "She has no concept of depth, which to me … I just don't get it."

All jokes aside, though, she raved about motherhood and said that children were basically the hot topic on the set of "Bad Moms."

"[Motherhood] is awesome," she said, with the film's co-stars next to her. "I feel like that's all we ever talk about when we get together. We talk about kids. We're all very lucky though. We all have little ones. It's great."
