Less than a month after reports of their engagement surfaced, it seems that actors Ashton Kutcher and Mila Kunis are also expecting a baby.

An insider reportedly confirmed the news to E! News after Friends With Benefits star Kunis was spotted attending a prenatal yoga class in Hollywood.

A friend tells People.com the actors “are both very, very happy” about the pregnancy, but denied rumours that they are expecting twins.

They were last seen locking lips for the Kiss Cam at an LA Clippers game on Saturday.

The former 'That 70s Show' co-stars have been together since April 2012 and sparked speculation they were engaged earlier this month after the brunette beauty was pictured with a diamond sparkler on her ring finger.  - IOL and Bang Showbiz
