The actress' bubbly jive drew audience applause, but all three judges agreed thatshe was a little flat-footed.
Even with the criticism, Inaba said Riley set thebar last week and continued to wow them with her performance.
The TV host earned cheers for his paso doble, and judges - who gave him the lowest score of the night last week - said they saw improvement.
Although Nye's routine lacked some technique, posture, movement quality and hold...
...judges added that he liked the fun the star put into his routine.
Nye earned 17 points, for a two-week total of 31 out of 60.
Based on their performances last week plus their audience votes, comedian Bill Engvall and Keyshawn Johnson were both in the bottom two, putting them in jeopardy of being eliminated.
Johnson had the second-lowest judges' score of the night last week for his cha-cha.
When he learned he was going home, Johnson said he was happy to have had the experience.
