Baby on board!

The first images of engaged stars Mila Kunis and Ashton Kutcher's TV reunion on "Two and a Half Men" indicate that the couple (who are also expecting a baby) still have the onscreen chemistry from their "That '70s Show" days.

The 11 photos from the recently taped episode align with what we know about Kunis's guest appearance on her fiancé's CBS sitcom: The actress plays Vivian, a "a young, beautiful, free-spirited world traveler who shows up on Walden's doorstep."

This is the first time Kutcher and Kunis have shared the small screen together since they played young lovers Kelso and Jackie on "That '70s Show," which ended in 2006. At the time, they weren't dating; their relationship didn't begin until 2012. They became engaged earlier this year and are expecting their first child.

Judging by the pics, Walden is surprised to see Vivian. In other images, he shares a Chinese takeout meal with her and confronts her in front of the tent she seems to be living in.

And as the casting notice teased, Walden instantly becomes smitten with Vivian and feels she might be "The One." The only problem is that he was about to propose to someone else!

In the juiciest photo of all, Walden (wearing a jaunty sailing outfit) mans the wheel of a yacht — with a lingerie-clad Vivian next to him!

Perhaps Walden throws that plan aside to follow his heart?

Watch the sparks fly between the real-life couple April 10 on CBS.
