Foxx announced the news in an Instagram post.
"My heart is shattered into a million pieces… my beautiful loving sister Deondra has transitioned," Foxx began. "I say transitioned because she will always be alive… anyone who knew my sis… knew that she was a bright light… I can't tell you how many times we have had parties at the house where she has got on the dance floor and stolen the show…"
