While the pool of celebrities continues to dwindle on ABC-TV's "Dancing with Stars," fans can take heart in knowing many of their favorites will return to the dance floor during the show's fourth annual tour.

"Dancing with the Stars - The Tour" is set to launch Dec. 17 in San Diego, CA, and make its way across the US, wrapping Feb. 8 in Philadelphia. The 37-city outing includes a stop in Toronto and a two-night stand in Uncasville, CT. Tickets go on sale beginning Nov. 10 and the full itinerary is listed below.

Meanwhile, the drama on the reality show continued to build last week as award-winning actress Cloris Leachman got the boot. In recent weeks, the judges had been gunning for the 82-year-old, who consistently received low scores but remained in the competition thanks to viewer votes, according to the Associated Press.

Celebrities remaining in the competition are television host/actress Brooke Burke, 'NSync singer Lance Bass, retired NFL star Warren Sapp, Olympic track star Maurice Greene, "Hannah Montana" actor Cody Linley and soap opera veteran Susan Lucci. Those eliminated in earlier rounds are Grammy-winning singer Toni Braxton, celebrity chef Rocco DiSpirito, reality-TV star Kim Kardashian, actor Ted McGinley and comedian Jeffrey Ross. Olympic beach volleyball champ Misty May-Treanor was forced to drop out of the competition after rupturing her tendon during rehearsals, according to reports.

In other DWTS drama, Linley's professional dance partner, Julianne Hough, went missing from the ballroom floor last week because she had surgery to remove her appendix, AP reported. Pro Edyta Sliwinska will fill in for Hough while she recuperates.

In addition to being the most demanding season ever, this year's "Dancing with the Stars" marks the largest cast assembled to date and features the oldest (Leachman) and youngest (Linley) competitors ever, according to a press release.

Starting this week, the competition grows more fierce as the dancers have to learn two new routines for each performance.
