Tissues to the ballroom floor, please!
"While we are all getting excited and looking forward so much to the finale next week, it will also be with a touch of sadness," Len said from the judges' table. "As this will be my last season judging on Dancing With the Stars."
As many in the ballroom gasped in disbelief, Len explained his decision.
"I've been with the show since it started in 2005," he said. "It has been a huge pleasure to be a part of such a wonderful show. I've decided I'd like to spend more time with my grandchildren and family back in Britain."
"I cannot thank you enough, the Dancing With the Stars family," he continued. "It's been such a wonderful experience for me. I'm looking forward so much to next week's finale. I'm sure it's going to be absolutely brilliant."
The ballroom gave Len a rousing standing ovation as Dancing With the Stars co-host Tyra Banks explained Len's influence, especially to the pro dancers on the show like Derek, Mark Ballas and Maksim Chmerkovskiy.
"You've inspired generations of dancers around the entire globe through your passion, your expertise and your laser-focused eye," Tyra said. "They are going to carry on that commitment to excellence forever."
