Kristin Cavallari was "really let down" when she reunited with her childhood sweetheart.
The 38-year-old reality star - who was married to Jay Cutler from 2013 until 2022 and has sons Camden, 12, Jaxon, 10, as well as nine-year-old daughter Saylor with him - was recently on tour and welcomed unexpected guest Johnny to the stage, whom she had dated in middle school, but was left disappointed by how things panned out.
