The Arquette family is mourning the death of Alexis Arquette.

In a Facebook post obtained by Wonderwall.com, brother Richmond Arquette confirmed the sad news that Alexis -- an outspoken actor, musician, cabaret performer and transgender activist -- passed away on Sept. 11 at 12:32 a.m. at the age of 47.

"Our brother Robert, who became our brother Alexis, who became our sister Alexis, who became our brother Alexis, passed this morning September 11, at 12:32 am," Richmond wrote on his personal Facebook page.

"He was surrounded by all of his brothers and sisters, one of his nieces and several other loved ones," Richmond continued. "We were playing music for him and he passed during David Bowie's Starman. As per his wishes, we cheered at the moment that he transitioned to another dimension."

"I am feeling immense gratitude to have been afforded the luxury of sharing life with him/her, for learning from Alexis, for being given the gift of being able to love her/him and to be loved by him/her. He was a force," Richmond added.

"He died as he lived, on his own terms. I am immensely grateful that it was fast and painless. It was an incredibly moving experience and I am humbled and grateful to have been able to have been with him as he began his journey onward," Richmond wrote, before concluding, "Thank you, Alexis, I love you and will love you always."

At 4:08 a.m., Alexis' sister Patricia Arquette tweeted, "Breaking through the veil singing StarMan."

Alexis came out as a transgender woman in 2006. Her transition was chronicled in the 2007 documentary "Alexis Arquette: She's My Brother."

Brother David Arquette shared earlier this year that Alexis had in recent months started identifying instead as "gender suspicious."

Boy George shared his sadness at hearing the news via Twitter. "So sad to hear of the passing of Alexis Arquette who played me in 'The Wedding Singer,'" Boy George tweeted. "My thoughts are with his family. R.I.P sister!" He later deleted that tweet and posted a new sentiment: "R.I.P my sister Alexis Arquette. Another bright light gone out far too soon. Love to the family and all that loved Alexis."

A source close to the Arquettes told Radar Online of Alexis, "She was in a coma for four days at Cedars [Sinai hospital in Los Angeles] and no one was allowed to see her except for family."

The Arquette family officially confirmed the sad news to TMZ, which also reports that Alexis had been battling an illness.

Hours after the sad news broke, the Arquette siblings -- who also include actress Rosanna Arquette -- released a statement paying tribute to their late sister.

"Alexis was a brilliant artist and painter, a singer, an entertainer and an actor. She starred in movies like 'Last Exit to Brooklyn,' 'Pulp Fiction,' 'Jumpin' at the Boneyard,' 'Of Mice and Men,' 'The Wedding Singer' and 'The Bride of Chucky.' Her career was cut short, not by her passing, but by her decision to live her truth and her life as a transgender woman. Despite the fact that there are few parts for trans actors, she refused to play roles that were demeaning or stereotypical. She was a vanguard in the fight for understanding and acceptance for all trans people," they wrote in the statement.

"She fiercely lived her reality in a world where it is dangerous to be a trans person -- a world largely unready to accept differences among human beings, and where there is still the ugliness of violence and hostility towards people that we may not understand," it continued.

The statement also gives a glimpse of how the tight-knit Arquette clan said goodbye. "In the days leading to her death, she told us she was already visiting the other side, and that where she was going, there was only one gender. That on the other side, we are free from all of the things that separate us in this life, and that we are all one," the statement reads. "She passed away surrounded by love. We held her and sang her David Bowie's 'Starman' as she punched through the veil to the other side. We washed her body in rose petals and surrounded her with flowers."

The family asks that in lieu of flowers or gifts, donations please be sent to organizations that support the LGBTQ community.
