Keo and the entertainer/reality TV veteran became the second couple ousted from the competition based on the combination of Dancing with the Stars judges' scores and home viewer votes they had received during last week's episode.
"Hello everybody. I am having a very good time. I enjoyed it very much. [Bruno Tonioli], I'll see you in the parking lot," Charo joked in her final words, referencing her playful feud with the judge over her low scores in the show's first couple of weeks.
Charo and Keo tied with another couple for ninth place on the judges' leaderboard last week after they received only 25 out of 40 points for their paso doble routine. She landed towards the bottom of the leaderboard in Season 24's premiere as well.
The Bachelor star Nick Viall and partner Peta Murgatroyd were the other couple in jeopardy last night prior to Charo and Keo's elimination; however, they were not necessarily one of the bottom-two couples based on judges' scores and America's votes.
Monday night's show featured the 11 remaining couples each performing one dance routine choreographed for "Vegas Night," which was a tribute to Las Vegas and all of its glamour.
Heather took the stage with DWTS Troupe member Alan Bersten again due to Maksim's leg injury. In an update, Maksim said he's walking again and quickly making strides. He hopes to make a full comeback by the end of the week and potentially return to the ballroom for next Monday night's show.
Heather and Alan performed the tango to "Toxic" by Britney Spears, while Nancy and Artem danced a sexy samba to "Shake Your Bon-Bon" by Ricky Martin.
Olympic gold medal-winning gymnast Simone Biles and partner Sasha Farber finished in fourth place on the leaderboard after they earned 32 points for their quickstep routine set to "Viva Las Vegas" by Elvis Presley.
Two-time World Series champion David Ross and partner Lindsay Arnold claimed fifth place. The couple received 31 points from the judges after they wowed with a Magic Mike-inspired jazz routine to "Candy Shop" by 50 Cent.
Nick and The Real Housewives of Beverly Hills star Erika "Erika Jayne" Girardi tied for seventh place on the judges' leaderboard with 26 points each.
Nick and Peta performed the tango to "Poker Face" by Lady Gaga, while Erika Jayne and partner Gleb Savchenko took the stage with a jive set to "Take Me to Heaven" by Patina Miller, Debbie Kurup and Amy Booth-Steel.
And last but not least, at 24 points, three couples tied for ninth place on the judges' leaderboard.
