Mila Kunis' acting days may be numbered.

The former "That 70's Show" star is expecting her first child with fiance Ashton Kutcher in the near future, and she's made it clear in the new issue of W magazine that she's putting motherhood first.

Kunis isn't planning on juggling movie and TV work (she currently voices the character Meg on Fox's "Family Guy"), saying that the idea of being a stay-at-home mom is very appealing to her.

"I had already decided to take a year off," she explains. "I have never wanted to be the person who only has business on her mind. To me, this job has always been a hobby that turned into a great profession, but I don't eat and breathe acting.

"I'm sure Meryl Streep has a very different point of view. But I'm excited about being a full-time mom."

The actress covers and is featured in the August issue of W to promote new film "Jupiter Ascending," which was unfortunately bumped from a late July release to February. She stars in the film opposite Channing Tatum, but couldn't give any details about the plot of the film during her interview.

She ended her interview with the magazine on a cute note, explaining that she had to pick up three of Ashton's cousins because she had a big surprise for them.

"I promised to introduce the girls to Channing," she explains. "They are so excited about meeting him.

"We all get movie star crushes," she added. "I'm marrying mine."
