Kelly Clarkson's daughter, River Rose, is only three months old, but the pop-country superstar is already instilling in her a love of country music! Last week, the singer brought her sweet baby girl to her very first concert, the Garth Brooks and Trisha Yearwood tour kickoff.

Clarkson recently collaborated with Yearwood on her new single 'PrizeFighter,' and has been making the rounds on country radio as the song tears up the charts. But the biggest leap for the 'Since U Been Gone' singer has been her jump into parenthood -- Clarkson and husband Brandon Blackstock welcomed their daughter in June. And in Chicago on Sept. 5, little River got to witness some of country's highest royalty in action!

Clarkson posted the precious pic of River wearing some pretty spectacular, glittery ear protection with a matching onesie. Yearwood's biggest little fan looks content in her cushy baby seat, sucking on her favorite WubbaNub, and we're guessing if she could talk, she would say how proud she is of her mama. Clarkson surprised the crowd when she took the stage with Yearwood after Brooks joked about singing her part of 'PrizeFighter' on her behalf. It was her first public performance since giving birth on June 12.
