Bindi Irwin and her partner Derek Hough emerged winners in "Dancing with the Stars" season 21. Meanwhile, Terri Irwin unveiled that her son is being eyed by the show's executive producers, according to Celebrity Dirty laundry. Robert, being just 12 years old may make it hard to him to participate in the show.

In an interview with E! Online, Derek Hough responded when asked whether he would come back for the next season, "I don't know, who knows? I have to say this isn't a bad way to go out."

On the other hand, Goodman is slated to come back for season 22 of "Dancing with the Stars" after being out for the last season. Goodman broke the news through his Twitter account. The veteran judge exited the show in season 21 because of the birth of his grandson in addition to an existing contract to a U.K. show "Strictly Come Dancing."

Meanwhile, "Dancing with the Stars: Live! Dance All Night Tour" commences on Dec. 15 and runs through Feb. 14, 2016, which will involve a visit to 43 cities across the country.

"Dancing with the Stars" season 22 is scheduled to debut on March 21, 2016 on ABC at 8.00 p.m. with a 2-hour premiere special. The show is an American dance competition show directed by Alex Rudzinski.
