"Len will not be returning as a judge this season on Dancing With the Stars due to his schedule as a judge on Strictly Come Dancing in the UK and the birth of his new grandson," DWTS executive producer Rob Wade told the entertainment news outlet earlier today.

No word yet on whether the series will bring in a new judge to sit beside Carrie Ann Inaba, Bruno Tonioli and Julianne Hough for the show's upcoming 21st season, which premieres on Sept. 14.
