Maci Bookout is pregnant and planning a wedding.

Pregnant 'Teen Mom OG' Maci Bookout Attends Bridal Event In London

Just days after Bookout's longtime boyfriend, Taylor McKinney, proposed, the Teen Mom OG star learned she was expecting her third child, and now, she's doing her best to juggle all of her responsibilities.

"I'm just trying to stay above water right now," Bookout joked to Reveal UK on Thursday. "I think I'm prepared. By pretty much the third one you know what you are doing... or at least you think you do!"

Earlier this month, Bookout flew to London to find the perfect wedding dress, and she and McKinney are on the verge of locking down a venue for their big day.

Although Bookout's engagement to McKinney was not filmed, she said her wedding would be.

"So far, that's the plan," she revealed. "[Catelynn Lowell] has given me some tips on having the camera crew and MTV be a part of it. That's been helpful. Filming is a lot of work, so having that added stress can be a little rough. She's been talking to me about how to handle it, so that's been nice."

"As of right now, Bentley is going to be like a mini best man and we're not sure for Jayde and the new baby just yet… we're still trying to figure out what would be best for them, considering they are going to both be so young," she added.
