Kelly Clarkson made her first post-baby appearance last night when she performed at the Garth Brooks and Trisha Yearwood concert in Rosemont, Illinois – and she brought along a very special guest.

Shortly before the concert, Clarkson posted a photo of daughter River Rose to her Twitter account.

Those floral pants! The bedazzled headphones! The tiny feet! Squeeeeee! Little RR has certainly grown since the last time we saw her, just days after Clarkson gave birth on June 12.

Clarkson guests on Yearwood's new song "Prize Fighter," which she performed with the country crooner last night – quite the first-time concert for River! And as for those headphones...

Do they come in adult size? Asking for a friend.
