Sabato Jr. is also one of many soap opera stars to compete on Dancing With the Stars, dating back to Season 1 when Kelly Monaco won the very first Mirrorball Trophy.

Also joining the cast for Season 19 is Duck Dynasty's Sadie Robertson, according to a new report by Us Weekly. She is one of the youngest contestants to ever compete at only 17 years old.

Several stars from other reality shows have competed on DWTS in the past, from former Bachelors to Kate Gosselin to Kim Kardashian to NeNe Leakes, most recently.

ABC has not confirmed any of these casting reports.

The rest of the cast who will be competing on Dancing With the Stars next season will be announced live on ABC's Good Morning America on Thursday, Sept. 4.

Dancing With the Stars Season 19 begins Monday, Sept. 15 at 8 p.m. on ABC.
