William Levy and Maria Menounos tied for the night's high with 59 points apiece, as both posted perfect scores of 30 Monday, with William delivering a sexy samba and Maria showing her mastery of the tango.
Bruno Tonioli described Maria's perfect dance as "titillating, enticing and absolutely fabulous;" the Extra host's follow-up jive was a near-perfect 29 points.
William's first dance, the tango, got him 29 points; the "Cuban Brad Pitt's" perfect samba had judge Len Goodman raving, "I've never looked at a man's bum for so long in my life!"
Bruno told William, "You were like the dictator of the tango!"
No stranger to pressure-filled Monday nights, Donald Driver delivered 57 points on the evening with a 28-point tango and a 29-point samba judge Carrie Ann Inaba gave him a 10 for, telling him "I just thought that was A-plus."
Driver's Green Bay Packer teammates Aaron Rodgers and Clay Matthews were at the tapings cheering on the trusty receiver.
Katherine Jenkins surprisingly wilted under pressure Monday: the mezzo-soprano stunner started off strong with a 29-point quickstep, but her 27-point salsa was marred by a misstep at the end of the routine, leaving her in tears with the night's low of 56 points.
"I'm sorry at the end, but I just love seeing you push your boundaries," Carrie Ann told a sobbing Katherine, who repeatedly apologized to her partner Mark Ballas after the disappointing showing.
Katherine tweeted after the show she was with a doctor who diagnosed her with "a reflectorical spasm in her lower back."
In any event, Len's prediction this season's was "going to be the best semi-finals ever" certainly rings true after Monday's impressive display.
