Kelly Osbourne, daughter of Ozzy and Sharon Osbourne, has apologized to the transgender community.

In an op-ed published Friday at the blogs of the Gay & Lesbian Alliance Against Defamation (GLAAD) and The Transadvocate, the 27-year-old Osbourne apologized for calling transgender model Elle Schneider a “tranny” during a recent interview with Glamour UK.

“As a lifelong LGBT ally and friend, I feel it is my duty to not only apologize for my wrong but to also correct it,” Osbourne wrote. “The word 'tr*nny' is a derogatory and hurtful word. I was completely ignorant to this and soon came to realize most of my peers and LGBT friends are too. This is a word I will no longer use or allow.”

“Transgender people are some of the bravest people on Earth and among the LGBT community. I cannot imagine the courage it takes to live your life openly and honestly, reflecting who you truly are, or the hurt that comes from having to hide who you are because others may not support and accept you,” she added.
