Kelly Clarkson's baby girl, River Rose, might be only three months old, but she has already attended her first concert -- and she got to hear her mom perform as well.

Garth Brooks and his wife Trisha Yearwood were in Chicago on Sept. 5 for the second of 11 shows in the Windy City as part of their recently-launched world tour. As Yearwood was getting ready to perform her new single 'PrizeFighter,' a duet with Clarkson, Brooks dead-panned, "Hey! I’m going to be Kelly Clarkson tonight! I can sing better than Kelly Clarkson," before the songstress walked on stage to thunderous applause.

Apparently, Clarkson's daughter enjoyed the show as well, as the Season 1 winner of 'American Idol' shared on Twitter after the concert.

'PrizeFighter' is the title track of Yearwood's upcoming album, which will be released on Sony Nashville. The single will be released nationwide on Sept. 15.
