Kim Zolciak remains in Atlanta and will not appear on Monday's Dancing With the Stars following a mini stroke she suffered last week, ET has learned.

A source close to Kim tells ET that the reality star was not able to fly, while another source confirms her appearance on Monday's show has been cancelled. It is unclear whether the 37-year-old, whose health scare last Wednesday has kept her from the dance competition, will be able to continue on the program.
