Mila Kunis Pregnant? Ashton Kutcher's Girlfriend 'Taking Pregnancy Vitamins'

American actress Mila Kunis is reportedly trying to get pregnant with her boyfriend Ashton Kutcher.

According to OK! Magazine, Kunis and Kutcher are ready to start a family and the Black Swan actress has reportedly been taking pregnancy vitamins.

"Mila and Ashton have been trying for a baby for months" a source said. "She's gained 10 pounds and is taking pregnancy vitamins. The buzz is that she is looking like she could be carrying a baby.

"Lately, you can't even wipe the grin off Ashton's face! The atmosphere around them is just electric."

The pair, who played characters Michael Kelso and Jackie Burkhart on hit sitcom That '70s Show, have been talking about having children for some time now.

"It all came together when Ashton showed Mila a picture of a baby in a magazine and said he wanted to dress their baby in that style," a source told the publication.

"Mila giggled as she cradled her stomach. She was glowing the entire time that she got her pedicure!"

Kutcher and Kunis are hoping to get engaged as the former's divorce from Demi Moore was finalised recently.

Moore, 50, filed for divorce in November of 2011 after Kutcher reportedly cheated on her with 23-year-old student Sara Leal.

"They both want babies. It is something they are vocal about. I cannot imagine it will still be very long before Mila gets pregnant" an insider source close to Kutcher told People magazine.

"Maybe [the pregnancy will happen] right after they get engaged, if not even sooner. Ashton is certainly planning a proposal. They are incredibly affectionate and it is completely effortless."
