Dancing with the Stars' seventeenth-season cast is apparently beginning to leak out.

While ABC will only officially announce Dancing with the Stars' upcoming cast September 4 on Good Morning America, half of the dozen celebrity participants have supposedly been outed.

Dancing with the Stars will feature actress and The Talk co-host Leah Remini, actress Valerie Harper, Jersey Shore and Snooki & Jwoww star Nicole "Snooki" Polizzi, actress and former Step It Up and Dance host Elizabeth Berkley, actress and Glee star Amber Riley, and singer and The Voice social media correspondent Christina Milian, TMZ reported.

Harper, 74, made headlines back in March when she revealed she has terminal brain cancer and likely had no more than three months.

Milian's inclusion in the cast, if accurate, would seem to indicate she won't be part of The Voice's upcoming fifth season, as the reality singing competition will air live simultaneously against Dancing with the Stars on NBC on Monday nights.

NBC did not immediately respond to an inquiry regarding Milian's status on The Voice.

Dancing with the Stars' seventeenth season is set to premiere with a two-hour broadcast on September 16 at 8PM ET/PT.
