Maynard is a mother to six children: Jones, Nola, Gibson, Gatlin, Jennings and Ricki.
The former Bachelorette star's daughter Ricki Hendrick announced that she's expecting her first baby, a daughter, via her Instagram Stories on Tuesday, Aug. 26. In the first post, the 20-year-old shared a screenshot of her phone's lock screen, showing a photo of her sonogram.
"'Netflix told me I'm not allowed to talk about it' - Huda," Ricki wrote in text next to the photo, alluding to comments made by Love Island USA's Huda Mustafa at the season 7 reunion.
In her second slide, the soon-to-be mom showed a short clip of an ultrasound showing her baby girl moving in her belly. Ricki shared that her "heart is so full," joking that her stomach is not.
"My heart is so full, yet my stomach is so empty because she hates all food. i'm convinced," she wrote over the clip.
Maynard Johnson did not immediately respond to PEOPLE's request for comment.
Maynard Johnson, 39, is also mom to Jones, nearly 3, Nola Belle, 4, Gatlin, 7, Gibson, 8, and Jennings, 10, who she shares with husband Tyler Johnson.
The proud mom, who shares Ricki with her late fiancé Ricky Hendrick, reflected on how much her daughter has grown up for her 19th birthday in 2024. She shared a pair of photos on Instagram that display just how far her mother-daughter bond has come with her eldest child.
Maynard Johnson opened her Instagram post with a snapshot of herself and Ricki walking into a venue together. The mom of six could be seen with an arm around her daughter's shoulder while her daughter wrapped an arm around her mom's waist. The photo appeared to have been taken sometime around her high school graduation, as Ricki was holding a graduation cap in her hand.
The second photo was a throwback to when Ricki was a preteen. In the snap, the mother-daughter duo could once again be seen walking together, as Maynard Johnson rested an arm around Ricki's shoulder.
The pair of pictures highlighted Ricki's growth over the years, as in the second photo, she appeared to be much smaller, while in the more recent photo, she shared the same height as her mom.
"My beautiful girl. I'll always and forever have your back," Maynard Johnson captioned the birthday tribute post. "I love you and am so proud of the person you are. Happy 19th Birthday @rickihendrickk You're a gift to the world!"
