Thomas Rhett

The newborn will join older sisters Willa Gray, Ada James and Lennon Love when she arrives in November.

At a recent stop on Kelsea Ballerini's tour with the Jonas Brothers, Ballerini was joined by a surprise guest.

Just in time for Father's Day, the musical father-son pair are joining forces for a sweet duet.

Rhett's three daughters have since come around to the idea of a baby sister -- but maybe they'll still get a baby brother one day.

Way to go, Willa Gray!

Something changes with each picture. Do you see it?

Thomas Rhett shared the news onstage in Texas ... and he also shared the sex of the new baby.

"I think when you have kids, you have this whole other sense of gratefulness for what your mom did for you growing up," the singer says.

"I got emotional just watching her get emotional."

Rhett and wife Lauren's late friend Hunter is the inspiration behind this new song.

“I can’t even put into words what getting back out on the road means to me, my band and crew."

The title track to his upcoming album represents the tone and theme of many of the 11 songs.
