Maci Bookout's Instagram

"I honestly don’t think it has actually 'hit' me yet," Bentley and Jayde's mama -- seen smooching her new fiancé in the photo above -- exclusively told MTV News shortly after the proposal. "But I am very excited and feel super blessed that I get to marry Taylor. He’s an amazing man and dad."

So how did Taylor pop the question? A hint: It wasn't at the barber shop!

"We were on Venice Beach!" the blushing bride-to-be reveals. "He (and MTV) had told me that I was going to do an interview for MTV.com, which turned out to be a complete trick just to get me to the beach for him to ask me."

She continues: "When he asked me to marry him, I was in complete shock. I couldn’t believe that it was actually happening, and to be honest, I couldn’t believe that he had pulled it off without me figuring it out...because I usually know everything!" Way to pull off the ultimate surprise, Taylor!

Fittingly, Maci's two munchkins were on hand for the unforgettable event -- and her firstborn was (adorably) overwhelmed by what was happening.

"He was shocked and emotional," she dishes. "He actually teared up a little bit -- I think his exact words were that he was just so happy that T-Money was finally going to be his step dad."

Understandably, her infant's reaction was a bit more subdued.

"Jayde was pumped considering she is only eight months old," the Tennessean jokes. "She has no idea what’s really going on."

Viewers first got a glimpse of Maci and Taylor's relationship during the past season of "Teen Mom OG" -- from bonding time with Bentley and learning that they were expecting their own little girl to moving into a brand-new home to begin their future life as a family of four and beginning their own business, the duo's exciting milestones have unfolded on the small screen. Now, we can add another very big, and wonderful, occasion to their incredible story. And, of course, Benny and Jayde will play a part in the nuptials.

"Taylor has asked Bentley to be his 'mini' best man, and Bentley agreed," Maci says. "Not sure he is aware of the responsibilities of a best man, but I’m sure he will do just fine! Jayde will definitely have a part in our wedding too -- it’s just a matter of figuring it out considering she is still so young. I am excited to have them share this day with us."
