Chiller had said Kyrgios and fellow tennis player Bernard Tomic were "on watch" to represent Australia at the Rio Olympics after several recent behavioural incidents.
Kyrgios responded by tweeting: "Someone tell that Kitty chiller to watch that tweener lob, then she will understand why I'm on watch for the olympics lol #smh."
