Mila Kunis is pregnant.
The 30-year-old actress is expecting her first child with That ’70s Show co-star Ashton Kutcher, to whom she recently got engaged.
A source told People.com: "They are both very, very happy. It’s still early."
The couple sparked engagement speculation after Mila was spotted with a huge diamond ring last month, but the loved-up stars aren’t expected to rush down the aisle in light of their baby news.
The insider added: "It won’t necessarily be a short engagement. They haven’t begun planning the wedding yet."
Meanwhile, E! News reports that Mila was recently seen at a prenatal class in Los Angeles.
The couple began dating in 2012 following Ashton’s split from ex-wife Demi Moore, but they have known each other for years after playing the lead roles in hit 1990s sitcom That ’70s Show.
Ashton, 36, is thought to have had a crush on his gorgeous co-star when they worked together, but their romance didn’t blossom until years later.
A source previously said: "He was so in love with [Mila] for a while when they worked together. He thought she was a goddess, was always talking about how beautiful she is."
Mila recently opened up about her low-key date nights with Ashton, revealing they enjoy "white T-shirt nights."
She explained: "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.
"Nothing fancy, it’s just something that you love to do—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."
