Maci Bookout Claims Her 'Teen Mom OG' Feud Was With MTV -- Not Farrah Abraham

Bookout and McKinney welcomed their first child, Jayde Carter, on May 29, over two years after they began dating. Although the couple's relationship was long distance at first, McKinney moved to Tennessee to be close to Bookout last summer, and months later, Bookout discovered she was pregnant.

Days ago, also on Instagram, Bookout shared a photo of herself with fans, and discussed her parenting duties.

"#Selfie...Because today in between all of the diapers and bottles for baby Jayde, I actually brushed my hair and put a little make up on just in time for Bentley's baseball game," she wrote. "I've realized that parenthood is hard work at any age, and that's why it's so important to wait until you're really ready to start a family. I can't help thinking how much more prepared I feel this time around."

As for the ring on Bookout's finger, it's unclear whether or not it is an engagement ring. However, Bookout made it crystal clear that she wants to marry McKinney during Teen Mom OG.
