'Dancing with the Stars' season 22 cast news: Bindi Irwin's brother may be joining the show

(ABC website)Official cast of "Dancing with the Stars" season 20.

Bindi Irwin won "Dancing with the Stars" season 21 and made some record-breaking stints along the way. And now, rumors have been floating around that her little brother, Robert Irwin, may follow in her footsteps.

Robert "Bob" Irwin is the latest name to ring in the rumor mill of who will be joining the cast of the upcoming season of "DWTS." Reports are saying that his sister's victory may have inspired him to perform on the ballroom stage. His and his mom's frequent visit to the live stage every time Bindi would perform may also have heightened his interest in joining the show.

In case he will really be competing, he has big shoes to fill, following his sister's triumph. Bindi Irwin is quite a record breaker. At 17 years old, she is the youngest winner of the show alongside Shawn Johnson, who won in 2009. She also holds the record for getting the most perfect scores from the judges, with eight under her belt.

Other names rumored to be joining the roster of stars for "DWTS" season 22 are "The Bachelor" star Ben Higgins, NFL player Rashad Jennings, and "Chasing Life" actress Italia Ricci.

In a press conference held for "The Bachelor" 2016 installment, reporters asked Higgins if he would ever consider joining "DWTS." The 27-year-old software salesman answered, "I don't know what to expect next and I'm open to anything... I love my life here in Denver. I don't want to chance my life, but if there's opportunity to enhance it, I'm all for it!"

Jennings, on the other hand, revealed his interest in participating in the show. In his interview with TMZ, he said he would love to do it "when the time is right." For now, the football player is focused on the sport. However, he told TMZ he has been in talks with ABC, and the possibility of him in the competition "is going to end up happening."

Season 2 of "Dancing with the Stars" is set to premiere on March 21 on ABC.
