As we reported yesterday, actress, model, and transgender activist Alexis Arquette passed away at 12:32 am on the Sunday morning.
Though no official cause of death has been revealed, sources have indicated that Arquette died from complications from AIDS.
Some insiders have claimed that she had also been diagnosed with an inoperable tumor.
Her family has not confirmed the cause of death, but in the social media post in which he announced her passing, Alexis' brother Richmond Arquette did indicate that she had been battling an illness and recently took a turn for the worse.
"Our brother Robert, who became our brother Alexis, who became our sister Alexis, who became our brother Alexis, passed this morning," Richmond wrote.
"He was surrounded by all of his brothers and sisters, one of his nieces and several other loved ones."
He added that Alexis had outlined for her family exactly how she wanted them to pay their respects:
"As per his wishes, we cheered at the moment that he transitioned to another dimension," he revealed.
The claim that Alexis was suffering from both cancer and AIDS comes from a former boyfriend named Robert Dupont, who added that the 47-year-old was in a medically induced coma at the time of her death.
Other sources have since confirmed that Alexis had been diagnosed with AIDS.
Now, Alexis' famous family members are paying tribute on social media and planning for a funeral that they hope will serve as a fitting tribute to her unique spirit.
"Alexis's family are very close and they are planning a private service of their own this week in L.A., followed by a very private burial service," a source close to the Arquettes tells Radar Online.
"Alexis is expected to be buried this week in L.A. and the Arquette family has asked, that in lieu of flowers, her friends and fans donate to LGBT causes and charities."
On social media, meanwhile, David Arquette has been thanking fans for their support and sharing fond memories of Alexis.
"Thank you all for your love and kind words about Alexis," the actor tweeted this afternoon. "My hero for eternity."
Patricia Arquette tweeted recordings of several of Alexis' favorite songs, including David Bowie's "Star Man", which the family says was playing at the moment she passed.
"Breaking through the veil singing StarMan," Patricia tweeted.
In addition to her acting, Alexis was a talented painter and singer.
She is best known for her roles in such films as Last Exit to Brooklyn, Pulp Fiction, Of Mice and Men, The Wedding Singer, and The Bride of Chucky.
