Mila Kunis Pregnant: 30-Year-Old Actress And Partner Ashton Kutcher Have An Unusual Pregnancy Exercise; They Opt To Try Something Fun!

The pregnant Mila Kunis and her partner, Ashton Kutcher, are ballroom dancing!

While some pregnant women choose to do yoga and other light exercises, Mila opted to try something fun with her fiancé Ashton Kutcher.

The A-list couple prioritize health and safety among anything else.  According to a source close to the couple, "Ashton and Mila are taking a novel approach to staying healthy during her pregnancy - with ballroom dancing. They've been taking lessons for a long time now and find it's the best low-impact exercise for Mila as she balloons with their first child."

The couple's bold move was reportedly inspired by one of their favorite movies, "The Silver Linings Playbook," starring Bradley Cooper and Jennifer Lawrence.

"Ashton and Mila don't do anything complicated. They just do easy moves in fun ballroom dance classes that they took to have something different to do together. They're happy they did because it's great exercise for Mila. Mila may have to stop dancing as she nears her date, but right now she and Ashton are really enjoying it - even though Ashton does get a little red-faced when their friends find out!"

The couple announced their engagement early this year.  News about Mila Kunis' pregnancy spread like wildfire after it was first reported on E! Online with their fans begging for more information.  The child will be both Ashton's and Mila's first.

The engaged couple spent eight years, from 1998-2006, working together on "That 70′s Show."  Fans of the show had hoped that the two stars would get together in real life as they quickly became the more famous of the cast mates.

Before Mila and Ashton started dating in 2013, Mila was dating actor Macaulay Kulkin while Ashton was married to actress Demi Moore.
