They're exhausted and they're excited. And like all five couples in the top five, Osbourne and her partner are planning to give it all they've got.
"Now that we are in week eight its almost those last few miles so it becomes less stressful and more exciting," said Van Amstel.
"The fear has turned into fun because I'm at a point now where no matter what happens, whether I make it into the finals or not, I feel like I've done so well and I've learned so much," said Osbourne. "I've grown so much that now I'm not stressing myself out anymore. I just want to have fun with it."
With one of their two dances on Monday night, they'll be having some "flashback fun."
"We have a 1960s Jive, and we're doing it to Ike and Tina Turner's 'River Deep Mountain High,'" said Osbourne. "I love the 60s, I'm such a big fan of A-line and mod and movies like 'Quadrophenia' and 60s go-go, and all that. For me the 60s play a big role because it kind of created what rock 'n' roll is today."
/*Donny Osmond*/ and /*Kym Johnson*/ are also going to embrace a blast from their past.
"We have an 80s inspired Paso Doble next week and we are going all out with the costumes, hair and makeup," said Johnson.
/*Joanna Krupa*/ and /*Derek Hough*/ are going back to the future.
"It's cool, it's gonna be good," said Hough.
