Mila Kunis and Ashton Kutcher have expanded their household again!

The parents of 1-year-old Wyatt -- with another little one on the way! -- added an Amazon Alexa system to their home recently. Ashton was so pumped with the new arrival that he took to social media to share his excitement.

"Thank you Amazon for tricking out the house with Alexa. Truth.. it's extremely useful! #alexa #kit #nightrider #echo #amazon," Ashton captioned his video and showed off how to use it.

"No Ashton, your wish is my command," the device says to him before he explains that it's basically like a "kit car for all you 'Knightrider' fans."

The device can do everything from turning your lights on to reading you the news.

At one point, Alexa says to Ashton, "Whatever you need, I'll take care of it. You know that's true."

Ashton hilariously responds, "Alexa, you're getting a little frisky!"

But as much fun as he's been having with it, Alexa will serve as a convenient tool for when they bring home their second baby.

"They wanted to do this before the baby came, and they love it," a source told Us Weekly. "Their entire house is now voice-activated. Every part of it works by command of their voice. It took weeks to do it, but it's amazing now and they love it."

Ashton and Mila first announced that they were expecting in June 2016, and the "Bad Moms" actress has been talking all about her pregnancy while promoting the movie.

She recently opened up to Kelly Ripa on "Live With Kelly!" about how this pregnancy has differed from her first when it comes to her cravings.

"With the first one I didn't have any aversions. I craved sauerkraut. The first half of my pregnancy, I couldn't get enough vinegar. Greek chopped salad: vinegar. The second one, I can't eat meat. It'll look delicious to me, and then I'll take a bite of it, and then I'm like, 'Uh-uh. Can't do it.'"

She continued, "This is going to offend a lot of people who are vegetarian: I love steak. I could eat ground beef—like a burger, I can eat—but whole pieces of meat, uh-uh. Uh-uh. It doesn't make any sense. But I can also eat eggs all day long. If someone's like, 'Have an egg for dinner!' I'm like, 'Great.' It's a very strange pregnancy when it comes to, like, food."

In spite of the unusual cravings, Mila told Ryan Seacrest on July 29 that she's feeling "great" and hasn't ruled out having a third child just yet.

"After we had Wyatt, the second that I gave birth, I was like, 'I know that we need to have another baby,'" she said. "And so I always say after the second one, we'll know if we need to have another one. I really do believe you know when your family is complete."
