If this whole pop-star thing doesn't work out, Katy Perry may have a future in weather reporting. During an appearance on Australian TV on Tuesday, Katy gave the weather forecast with some amazing commentary: "Australia is a big country." Harry Potter fans will especially appreciate her forecast for Hobart, Tasmania's capital, which she hilariously referred to as "Hogwarts." The newscasters on Channel 7's Sunrise were really entertained by her segment — so was the in-studio koala — and Katy got big laughs with her observation on the "chilly" temperatures, saying, "23? That's really cold, y'all!" Watch Katy's full weather forecast above to see all her antics, plus what she really thinks of her wax figure: "Her boobs are much bigger."
