The room got heated during Latin Night on "Dancing with the Stars" on Monday, as 12 couples offered up their best footwork in hopes of making it to then next round.

The evening saw some contestants improve, while others experienced a drop in scores. Read on for some of the highlights.

Actress Elizabeth Berkley and Val Chmerkovsky got things under way with a samba that Len Goodman called "fantastic," earning the pair a score of 25.

"Glee" star Amber Riley and Derek Hough, the leaders from last week, did a jive that Goodman called "terrific," but they were criticized for "flat footwork," resulting in a score of 24.

Actress Leah Remini and Tony Dovolani impressed some of the judges with their samba. And it sounds like Remini has even more of a reason to strive for the mirrorball trophy "I'm going through a personal big change for me and my family," she told Dovolani in a rehearsal segment. "The church (Scientology) is looking for me to fail so they can say to their parishioners, see what happens when you leave."

Valerie Harper, who was diagnosed with terminal brain cancer earlier this year, danced the paso doble with pro-partner Tristan MacManus, a routine that had Harper looking a bit nervous. The judges pointed out that she made some mistakes, noting that she appeared a bit lost. They pair received a score of 19.

AndBilly Nye, last week's lowest scorer(and audience favorite), managed to get a standing ovation after his dance with Tyne Stecklein. The crowd even started changing "Bill! Bill! Bill" at one point, and Bruno said they "stepped it up" this week. That's true, considering last week's score of 14. Though there's still work to do, the judges said. They received a 17 on Monday night.

Landing in the bottom two this week were comedian Bill Engvall and Emma Slater and former NFL star Keyshawn Johnson and partner Sharna Burgess. In the end, Johnson got the boot.

"For a guy that's never even bobbed his head in the car, the fact that I could have the experience of dance... is something amazing to me," he said, adding he wished he could have done more to help Burgess out.

"DWTS" returns next Monday on ABC.
