"Dancing with the Stars" is still weeks away from the semifinals, but Katherine Jenkins is continuing to run away with the competition.
The Welsh classical singer once again dominated the dance floor - with partner Mark Ballas - topping the leaderboard twice in one night.
While she didn't quite earn that elusive 10 from Len for her first competition number with Mark - a super samba - Katherine did get some surprising praise from the Brit judge.
"I'm gonna call you the midwife - you keep delivering week after week," Len said as the pair took home 29 out of 30 points during Motown Week, for dancing to a live performance by The Temptations.
But the two proved they had not just the moves, but stamina as they tackled the marathon group round at the end of the show, and won.
A number featuring all of the couples, Katherine and Mark pulled out move after move with grace and sass, and kept it up long enough to win the coveted 10 points from the judges.
Before Katherine and Mark won the night, Jaleel White and Kym Johnson proved they were contenders once again, whipping out a cha cha that impressed the judges to the tune of 29 out of 30 points and a tie for first.
"You burned that floor. That was the biggest sizzler of the season," Bruno Tonioli said. "What doesn't kill you makes you stronger, and you've come back big time."
But Jaleel and Kym fell to third in the marathon round, after being overshadowed by William Levy and Cheryl Burke, and the former "Family Matters" star and his partner, fell to second overall for the night.
Hunky William and Cheryl had entered the marathon round in a tie for third (with Donald Driver and Peta Murgatroyd), but they managed to stand out from most of the competition with their smooth moves and a couple of stunts (like William ripping his shirt open, sliding across the floor, and dancing in front of the judges).
At the end of the number, William and Cheryl took second for the marathon round, 9 points and a final total of 36 points for the night.
The Leaderboard at the end of Round 1 was:
Katherine Jenkins and Mark Ballas performed the samba and were scored 29/30
