Multiple sources confirmed the news to Us Weekly with one of them stating that while the baby will be the first for both Kunis, 30, and Kutcher, 36, the latter "got plenty of practice with Demi [Moore's] girls."
Reports that the Friends With Benefits star was pregnant began in late March after she was spotted attending a prenatal yoga class in Los Angeles. The couple had been engaged for one month when the actress' pregnancy was revealed.
"Ashton is doting on Mila," a friend of the couple told Us Weekly, adding that Kutcher is already planning play-dates with the 2-month old daughter of the duo's That '70s Show costar Danny Masterson.
In recent weeks Kunis has hidden her baby bump is lose fitting dresses while attending Cinema Con in Las Vegas and the MTV Movie Awards in Los Angeles. An insider told the magazine that she "absolutely loves being pregnant."
Neither Kunis nor Kutcher have yet publicly acknowledged the pregnancy.
