The dancers are being secretive about the actual songs, but we'll hear tunes from shows including "Guys and Dolls," "Jersey Boys," "Rent" and "Grease."
"I've done musicals my entire life so I'm pretty excited for Broadway week. We have kind of an aggressive- ish dance so it'll be fun," said Lacey Schwimmer, hinting that her song with partner Chaz Bono is from Cher's (Bono's mom) favorite musical.
"I love Broadway. I did musicals when I was a kid -- I did 'The Rocky Horror Picture Show' and a few other things -- so I'm looking forward to it," said David Arquette.
The solo dances will include three Quicksteps, a Cha Cha, a Foxtrot, a Tango and a Rumba. The competitors will then split into groups, with each group performing to a medley of two songs, "Big Spender" and "Money Money."
"I'm a Broadway girl. I grew up going to Broadway shows and so yeah, it's a dream come true to be able to do it and do it with him," said Ricki Lake, adding that she loves her song and it's not from "Hairspray."
Monday's episode will also feature performances from Kristin Chenoweth and members from Broadway's "Sister Act."
Carson Kressley won't be taking part in Broadway week. He was booted last Tuesday after his 80s Jive didn't jive with either the judges or viewers.
"We came, we saw, we bedazzled," Kressley said. He and partner Anna Trebunskaya did so for at least five weeks of competition.
He may not have received the highest scores, but he did receive plenty of praise from his fellow castmates.
"It's not going to be as fun of a show without him," Bono said.
Broadway week on "Dancing With The Stars" begins at 8 p.m. on ABC7.
