Thomas Rhett shares humorous photo of candid moment between his 2 youngest daughters

As a father to four young children, Thomas Rhett is well-versed in living with babies, but it looks like one of his daughters is adjusting to her new role as big sister.

The hit singer took to social media to share a humorous photo of himself with his 1-year-old daughter, Lennon, sitting next to their newest addition to the family, 1-week-old Lillie.

The photo shows the new baby in a state of distress, crying next to her big sister on the couch, with Lennon giving a look to the camera that suggests she's clueless on how to handle the situation.

"Lennon is taking this really well," the "Country Again" singer captioned the candid moment.

"lol! the look on her face is 'what is that noise and what am i supposed to do about it?!!' sweetie," one fan writes in the comment section of Rhett's Twitter post, while another shared, "Priceless! I would definitely get the picture framed. Precious babies!"

Thomas and his wife Lauren welcomed Lillie on Nov. 15.

She is the couple's fourth daughter, following 6-year-old Willa, 4-year-old Ada and Lennon, who was born in February 2020.

In Rhett's announcement about Lillie's birth, he wrote, "7.5 pounds of pure joy🙌 @laur_akins you are my hero. Watching a child being born is legit a miracle. 4 under 6 here we go!"
