They say two's company and three's a crowd, but "Teen Mom" star Maci Bookout wouldn't mind adding one more to the mix in the form of a fourth child.

"I wouldn’t say there’s a plan," Maci told HollywoodLife in reference to her family goals. "I mean, we are definitely still open to adoption in the future, but no, I mean, we don’t have a plan."

The 28-year-old reality star and her husband, Taylor McKinney, have three children: Maverick, 3, Jayde, 4, and 11-year-old son, Bentley, from Maci's previous relationship with Ryan Edwards. While they are open to more, how that could potentially happen is up in the air.

"We’re still on opposite sides of the fence as far as biological children are concerned," Maci shared.

"We both are definitely still very interested in wanting to go the adoption route," she continued. "So, for now, we agree to disagree on biological children, but we’re definitely in the same boat when it comes to adoption."

The "Teen Mom OG" cast member went on to echo the same sentiment to E! News and revealed that even though she and Taylor agree on adoption, that doesn't mean it's happening anytime soon.

"We know it's one of those things like it's never the right time," the TTM Lifestyle designer said. "You can never be fully 100% ready or prepared but at the same time, we know we are not even close to that time or that happening right now."

Maci explained that she would like to wait until her younger children, Jayde and Maverick, are a "little bit older" and in school before bringing in a new member.

"We want to make sure we've got a good grip on our current family," she explained.

"Teen Mom OG" airs Tuesdays at 8 p.m. ET on MTV.
