"Teen Mom OG" Star Maci Bookout and Taylor McKinney Are Engaged -- Check Out Her New Bling!

Maci Bookout took to Instagram to announce that she's engaged to boyfriend Taylor McKinney.

"Well y'all, my best friend asked me to marry him! I'm one lucky lady, I love you T! @tmon3yyy," she captioned a pic where she's seen kissing her hubby-to-be. The reality star also flashed her new diamond engagement ring for the first time.

"I honestly don't think it has actually 'hit' me yet," the mother-of-two told MTV News 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."

It seems McKinney tricked his future bride by telling her she needed to shoot an interview for "Teen Mom OG," but he was actually planning to pop the question on the beach in Venice, Calif.

"When he asked me to marry him, I was in complete shock," she told the outlet. "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!"

Maci's two kids, Bentley and Jayde, also were on hand during the proposal.

“He was shocked and emotional,” she said of her son. “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. Jayde was pumped considering she is only eight months old. She has no idea what's really going on.”
