Contestants for Season 19 of ABC’s Dancing with the Stars haven’t been announced yet, but that doesn’t stop the speculation from starting. The rumors are now really heating up ahead of the Sept. 4 announcement of the cast on Good Morning America.

One of the stars rumored to be joining the cast this season, which starts Sept. 15, is General Hospital star Antonio Sabato Jr., according to E! News.

In addition, pro athletes and even a former Olympian are rumored to have joined the cast.

Bachelorette Andi Dorfman, American Ninja Warrior’s Kacy Catanzaro, Olympic track competitor Lolo Jones and former UFC star Randy Couture will all reportedly compete, TMZ reports.

The professional dancers that are returning were announced earlier this month. It was also revealed that former dancer, Julianne Hough, will join the show as a co-judge with Len Goodman, Carrie Ann Inaba, and Bruno Tonioli.

“I'm so excited to be back with my Dancing with the Stars family again on a regular basis,” she said in a statement at the time.
