Mila Kunis and Ashton Kutcher are expecting a girl, reportedly.

Despite keeping a tight lid on their pregnancy, multiple sources have confirmed the news with Us Weekly reporting the pair is ecstatic about the baby’s sex.

Rumours about Kunis, 30, and Kutcher’s pregnancy have attracted attention since the news of their engagement broke.

This will be the first child for the Ted actress but Kutcher, 36, has “got plenty of practice with Demi’s girls,” a source told Us Weekly.

Over the moon about his daughter-to-be, “Ashton is doting on Mila,” a source told Us Weekly.

Another friend says Kutcher is already planning play dates with the couple’s That ’70s Show co-star Danny Masterson and his two-month-old daughter, Fianna, reports Us Weekly.

Keeping “mum” about their private life is nothing unusual for the former That ’70s Show co-stars.

When rumours of their coupling emerged in 2012, the mum-to-be originally denied claims they were dating.

Kunis said: “It’s absurd! A friend is a friend.”

Earlier this year The Black Swan star was spotted wearing a huge ring on her finger and E! News reported they plan to tie the knot.

Naturally news of the engagement fuelled pregnancy rumours, with E! News reporting that a reliable source can confirm the pair is expecting a baby.

Kunis attended the MTV Movie Awards this week wearing a loose-fitting black dress, under which the Friends with Benefits actress was no longer able to hide her baby bump.

Despite the obvious bump, the pair remain silent.

The star of Two and a Half Men explained his silence in an interview with Elle magazine last year saying: “I am going to do everything in my power to have this relationship be private.”

When asked about Kunis he said, “People will fill in the blanks however they want.”

While filling in the blanks has been made relatively easy with Kunis’s MTV appearance, a friend close to the couple has told Us Weekly, “Mila absolutely loves being pregnant.”

The actress has also reportedly been spotted attending prenatal yoga classes.

The Daily Mail reports: “The pretty brunette has been seen arriving at classes in Hollywood, which combine pregnancy safe yoga poses with dance and meditation.”
