Mila Kunis is working hard to get her banging body back before she and fiance Ashton Kutcher finally say "I do" in the summer.

The new mom who's hands are quite full taking care of daughter Wyatt, has been reportedly starting to do some easy workouts to get back on track.

As Radaronline reported (as featured on London Evening Standard), "She cannot wait to feel sexy again. She has started a very gentle cycle of postpartum yoga and going on walks with Wyatt until her doctors give her the green light to start intense workouts, which should be by the end of this month."

"She has been such a sport about this whole pregnancy thing. But she is eating extremely healthy right now and will only allow natural foods into her body as well as the body of her daughter. Mila is a tiny girl and already looks like her old self again, but she really wants to get her banging body back in time for the wedding," an insider added.

Mila and Ashton have also decided not to get a nanny, so that's definitely addtional sweat for the "Jupiter Ascending" star.

"We decided right away that we didn't want to have a nanny or a night nurse, and we're lucky enough that we have jobs where we can stay home and take time off where we need to," Ashton said in an interview on The Talk.

"I kind of have like a hero complex, and I'm somebody's hero now."

Reports have claimed that the engaged couple is set to exchange their vows at a lavish July 2015 wedding. No other particular information has been confirmed, but as far as rumors go, it sure looks like their "That 70s Show" co-stars will be a huge part of the wedding party.

Rumor has it that the couple is already set for a summer wedding with a whopping $2M budget to spend.
