There is evidence :

But one more thing. Amethyst uses shape shifting to tease Pearl and Greg, or just to have fun. She never asked "Got any requests?" to anyone other than Peridot and was happy to shape shift for HER. And when Peridot betrayed them, Amethyst attacked her because she believed Peridot was actually good and redeemed. Garnet and Pearl were just worried about what she would do, Steven and Amethyst were upset after trusting her deeply.
