Over Mother's Day Weekend 2021, Thomas Rhett and Lauren announced that they are expecting their fourth child  — and fourth daughter.

"Well... we are pregnant again!" he wrote in an Instagram post showing off his wife's baby bump. 

"Tonight when I was on stage in Fort Worth about to play 'to the guys that date my girls' my wife talked to me in my (ear monitors) and said 'you can tell them if you want' so anyways, now you know," he continued. "We are pumped to be having our 4th girl🙌🙌🙌.." 

"Same bed/kids/time/messy bun, different day, different matching pjs 💗 **post bath time photo op thanks to daddy's photography obsession 💕😍," Lauren captioned a photo with her daughters in matching heart pajamas. 

For Thanksgiving 2020, the family of five made their way to the beach for some quality time. "So thankful for a few days at the beach with just us 5 🥰 ," Lauren captioned a family photo on the beach. "Plus donuts, bike rides, dreamy sunsets, hot chocolate in Christmas pj's, tiny seashells, going to bed early & lots of sandy toes." 

The girls, well, volunteered their support for the Tennessee Volunteers at the start of the 2020 football season.

On Thanksgiving 2019, Akins reflected on her life before she had three children. "This day 2 years ago we were spending Thanksgiving in Uganda trying to get our first baby girl, Willa Gray, home💕-it was also 2 weeks before I got a "stomach virus" in Africa that actually turned out to be our second baby girl, Ada James💕," she wrote on Instagram.
