Robert Irwin and Alix Earle join the 'Dancing With the Stars' season 34 cast — here's everything we know about the new season so far

ABC revealed in April that wildlife conservationist and television personality Robert Irwin is joining the cast. He’s got a competitive edge, as his sister, Bindi Irwin, won season 21 of “Dancing With the Stars” with partner Derek Hough.

Last month, it was announced that conservationist and TV host Robert Irwin will also be joining season 34. He follows his older sister, Bindi Irwin, to the Dancing With the Stars stage, who previously won the competition in the show’s 21st season in 2015 with her partner Derek Hough.
