The former talk show host and her partner Derek Hough impressed the judges during the Halloween-themed show and scored a very respectable 27 out of 30 for their pasa doble routine and 26 for the group dance.
During rehearsals, Ricki injured her rib but she battled through the pain for the performances.
Speaking about her injury, she said: "I'm in this corset, so it feels like it's held together, but you know it's bruised. But everyone has injuries at this stage."
Rob Kardashian and his partner Cheryl Burke impressed the judging panel - which is comprised of Len Goodman, Carrie Ann Inaba and Bruno Tonioli - with their tango routine, for which they dressed up as characters from TV series 'The Addams Family'.
Len told the couple - who received 25 for their routine and 26 for the group dance: "I thought you did a terrific job, and this is a crucial week."
David Arquette also won rave reviews for his cha-cha-cha, earning an impressive 24 out of 30, but war hero J.R. Martinez was told his 'Ghostbsuters'-themed tango was "substandard"', even though he still scored 25.
Len said: "This was substandard compared to what I expect of you. It's your own fault.
"In the last three weeks you have set such a high expectation of yourself."
Nancy Grace and Hope Solo also competed and the next contestant to leave the show will be announced tonight (01.11.11).
