Work it, mama! In a new YouTube video, pregnant Lauren Burnham tried on maternity outfits for her husband, Arie Luyendyk Jr. — with whom she is expecting twins and already shares daughter Alessi, 20 months — and then let him rate them.

“Today I thought I would try something fun. I felt like putting makeup on and getting dressed,” Lauren said at the start of the clip. “Being pregnant, your body’s changing a lot, especially when you’re pregnant with twins. It’s changing very rapidly. I’m having to learn how to dress my pregnancy body now and it’s kind of difficult. But I think I’m figuring it out and learning my vibe.”

She added, “So yeah, I’m going to show you my pregnancy style and see what Arie thinks.”

Next, Arie chimed in to say that he’s seen his spouse — whom he met and fell in love with on Season 22 of “The Bachelor” in 2018 — in “some pretty awesome” ensembles, as well as “some pretty confusing things” as her baby bump continues to grow.

Lauren began her fashion show by slipping into a little black dress, chunky black boots, and a camel-colored trench coat.

“Oh, I like it. I like those boots. I think it’s really cute. Let me see that bump of yours,” Arie said before rating the getup a 9 out of 10.

While Lauren changed into another outfit, Arie took a moment to gush about the future mom of three. “I feel like Lauren, while she’s pregnant, is at her most beautiful. She’s obviously this stunning and very attractive woman. But for some reason, when she’s pregnant, I just love her pregnant belly and I love how she glows,” the race car driver-turned-real estate broker said.

“And, so, I think her style is really cool,” he continued. “And when she’s pregnant, she has to get really creative. I’m excited to see what’s next.”

Lauren then emerged in a tiger-print maxi dress and black leather jacket. “This one’s super flowy and comfortable. I like to have the jacket over my shoulders in case I get cold,” she noted.

“Looking good! I like it a lot. Something about the leather really adds to this,” Arie said, handing out another 9 rating to Lauren.

Elsewhere, the Shades of Rose designer — who is anticipating the arrival of a boy and girl this summer — donned a floral sun dress from her own fashion label paired with a denim jacket and white sneakers.

“So, this one’s more of a spring style and it’s also in my size I was wearing before I was pregnant, so it’s a little tight. But I was thinking it’s getting warm in Arizona,” said Lauren, who lives in Scottsdale with Arie. “It was 80 degrees yesterday. It’s going to be about time to pull the spring dresses out, so here is more of a spring look.”

Arie loved the casual number. “I’m going to go 10 out of 10 with this one because this is just your everyday super cute look. Yeah, you look really hot. Sexy!” he said.
