Mila Kunis pregnant, she and Ashton Kutcher expecting first baby

Mila Kunis and Ashton Kutcher are going to have a baby, E!Online reports.

While the news has not yet been announced officially by the couple or their representatives, the two are said to be ecstatic over the baby's arrival, expected sometime later this year.

A source confirmed the news to E!, which reports that the 30-year-old "That '70s Show" actor was recently seen attending a prenatal yoga class in Hollywood.

Last Saturday, the happy couple had a courtside seat in Los Angeles to watch the Clippers play the Detroit Pistons, with bystanders expressing surprise over Kunis' shape.

The news of pregnancy comes just a few weeks after the actress was photographed flashing a huge diamond ring while shopping with her mother at a mall in Los Angeles, a source later confirming to E! that Kutcher had proposed.

The brunette beauty once told Cosmopolitan, "I'll tell you-we have a thing called white T-shirt night and it's when you wear jeans and a white T-shirt and you go on a date." Kunis added, "Nothing fancy, it's just something that you love to do. And whether that's bowling or dinner or going to a cheese shop and have some wine or walking around. I think that's just the best thing to do - and sometimes it's just nice to stay home."

Kunis recently signed on to be the global spokesperson for Jim Beam, although it appears she will be unable to endorse the brand in her private life for some time.

Although 36-year-old Kutcher gained some experience with parenthood during his time married to Demi Moore, who has three daughters with Bruce Willis, this will be the first child for him as well as for Kunis.
