Jason and Molly Mesnick are just weeks from welcoming their first baby into the world, and while we don’t yet know whether the little tyke will be a boy or a girl, we do know one thing for sure. Molly and Jason’s baby is going to have an amazing nursery!

The Bachelor couple has enlisted the help of Season 5 Bachelorette Jillian Harris, who is an interior designer by trade, to lend a hand in all things nursery. Jillian has already tweeted a sneak peek of her and a pal planning the room, and on January 11, Wetpaint Entertainment spoke exclusively with Jason and Molly at Bachelor Mansion in L.A. to get the inside scoop on what the finished room will look like.

We started off by asking Jason for a bit of insight into what Jillian’s been up to in the nursery. His response: “Yeah, she’s working on it right now. I don’t know a lot about it. You have to ask her.”

Our bad. It sounds like this is more of a conversation for the lady of the house! “Yeah, she is,” Molly quickly pitched in. “She has been great to work with.”

Jillian has been working as a designer for years, and the Canadian native is currently hosting a new design and remodel-centered TV show called Love It Or List It: Vancouver. “She’s obviously extremely talented,” Molly says, “and it’s been nice having more of that personal relationship with someone who’s working on this with us to put together a beautiful room.”

Molly reveals that the color scheme for the room will be grey and white — a safe bet since the Mesnicks have decided not to find out their baby’s gender beforehand. Jilly also opted not to adopt any specific theme. Instead, Molly says, the room is simply, “very peaceful and serene and simple.”

All in all, it sounds like Molly couldn’t be happier with how her baby’s little nursery is turning out. “I love her decorating taste. I knew she was the right person for the job.”
