The final four contestants shimmied – and shined! – Monday night at the Dancing With the Stars semi-finals, where each couple danced two routines. The stars were in the spotlight during their first number, in which each performed a brief solo. And Jennifer Grey took a giant step closer to the mirror ball trophy when she picked up perfect scores for both routines and earned a combined total of 60 points.
The judges dished out straight tens for the Dirty Dancing star’s cha cha to Duffy’s “Mercy” with partner Derek Hough. Bruno Tonioli gushed that their “execution was flawless,” while Len Goodman praised the duo for their mastery of both technique and performance.
During the second half of the show, the judges once again awarded all tens for Jennifer and Derek’s waltz, which Bruno called “a gem of a performance.”
