The pageant contestant completely lost it during the Miss Amazon competition when it was announced the crown would be going to Carolina Toledo instead of her.
In a video from the competition, Sheislane can at first be seen congratulating Carolina, but she took that back moments later, when she stormed back towards the winner, yanked the tiara off her head, threw it on the ground and insulted her before she walked off stage.
Then, Sheislane hit Facebook to make it clear she wasn't sorry for doing it.
"Good night! I would like to clarify to all that MY PROTEST came from me, I don't need to go through others' heads, I'm woman enough to take what comes and face it head on. Those who follow my trajectory know that I am MISS AMAZONAS GLOBO 2013/MISS BRASIL GLOBO 2013 and SECOND MISS GLOBO INTERNATIONAL, YES SECOND."
"I fought hard for all these conquers that I have in my life and I don't accept injustice and I would never let something go unpunished, yes I expressed my rejection and the attitudes were seen during the preparation of MISS AMAZONAS 2015, I don't regret having protested, in most big contest these "problems" happen and go unpunished, I believe I have started a change from inside this great competition. I want something CLEAN and HONEST! I am Sheislane Hayalla and my attitude won't diminish me or make me less miss, I am human, there is blood in my veins and I'M NOT A HYPOCRITE. I thank all of those who sent positive messages and to those who sent negative thanks too. #weareallSheislaneHayalla."
