"Dancing with the Stars" duo Bindi Irwin and Derek Hough were back in action — for one night! On Saturday, Derek showed up to support Bindi and her family at the Steve Irwin Gala at the SLS Hotel in Los Angeles. The emotional and memorable evening, which honored Steve's life's work and raised money for the family's continued conservation efforts as Wildlife Warriors, was definitely a fun reunion for the "DWTS" winners.
