The pressure to perform is getting to Nancy Grace.
While rehearsing for Monday's instant jive on Dancing With the Stars, the 52-year-old HLN host lashed out at pro partner Tristan MacManus, 29. "Are you actually acting tired?" she snapped. "You don't have twins that get up at 5:00, and you don't have a full-time job and I do!"
"I'm tired of you," MacManus said.
"I'm tired of you, too! So there!" Grace shouted.
During her confessional, the Georgia native admitted that she's "got a lot working against" her on the ABC hit. "I'm not the youngest -- in fact, I'm the oldest in the competition. It's not easy. But you know what? I knew that."
Despite their best efforts -- including Grace's cartwheel finish -- the pair failed to impress the judges, who awarded them a mere 20/30 points. (Earlier in the night, they earned 24/30 for their tango routine.)
"Nancy, yours is a Cinderella story. You've come to the ball and you've lasted for eight weeks, which I commend you for," judge Len Goodman, 67, told her. "For me, it's midnight and it's time to go home."
Grace didn't take Goodman's critique to heart, telling co-host Brooke Burke, 40: "That's what the Wicked Witch said too, but Cinderella got her prince and managed to stay at the palace!"
While Grace and MacManus disappointed the judges, J.R. Martinez and Karina Smirnoff earned the first perfect score of Season 13 -- twice! Ricki Lake and Hope Solo tied for second place with 52/60 points, while Rob Kardashian came in fourth place with 51/60.
