Mila Kunis and Ashton Kutcher recently announced their engagement, and now sources are saying the couple are expecting their first child.

While the duo have not confirmed the pregnancy, Kunis was seen at a pre-natal yoga class recently and was photographed wearing a loose-fitting sweater that gave her the appearance of a small baby belly, setting off rumors like wildfire. And although they are both extremely busy with their careers, a source told Us Weekly that they have wanted a baby for a long time.

“This is something they both wanted. They are both so happy.”

The possible baby news comes just a couple of days after word got out that the couple didn’t really like each other that much when they worked together on “That ’70s Show”.

“Everyone shakes their head over the romance. Ashton and Mila were absolutely not friends during much of the making of That ’70s Show. In fact, they couldn’t stand working together. The two were never close on the set. Quite the opposite!” a source said.

Not the case these days, however, and their friends say they are really good for each other. Laura Prepon, who played Donna on the show, commented recently on their relationship even though that’s not something she likes to do.

“Yeah, I don’t usually comment on my friends’ personal lives,” she said. “But they’re an amazing couple.”
