Transgenderism is a psychological state or physical condition in which an individual rejects his assigned sex and embrace the one they prefer. The term transgenderism has become an umbrella word lately, but it is a lot different from expressions like transsexual, transvestite, trans-man, and trans-woman, etc. A transgender person is someone who dresses, behaves, and lives their life like a person of the opposite gender, whereas a transsexual goes under the knife to alter their physical appearance and restructure sexual organs. Being one of the four groups of LGBT community, transgender people represent the many walks of life. Have a look at 12 of the most famous transgender celebrities from around the world.
