‘Dancing With The Stars’ 2015 Spoilers: Leah Remini Replacing Erin Andrews During Week 6, ‘Famous Dances Night’

Leah Remini is headed back to "Dancing With the Stars," but this time it won't be for a chance to win Season 21's Mirror Ball Trophy. The outspoken actress and reality star reportedly has been tapped to fill in for Erin Andrews as guest host on Monday's show.

Andrews, who has been co-hosting the ABC competition show with Tom Bergeron since Season 18, will miss the upcoming performances due to other work obligations. According to E! Online, she'll be covering the World Series as a sideline reporter for Fox. The site reports that the 37-year-old is expected to return to "Dancing With the Stars" once the World Series is over in November.

This is the second time Remini, who competed on the show with Tony Dovolani in Season 17, has stepped in for Andrews. It's also the second time "Dancing With the Stars" has a guest host this season. Earlier this month, Season 19 winner Alfonso Ribeiro stepped in for Bergeron, who left to visit his sick father. Bergeron's dad, Raymond Bergeron, died Oct. 12 at the age of 81.

As previously reported, "Grease" star Olivia Newton-John is expected to guest-judge on the Week 6 episode, "Famous Dances Night," in which the celebrities will reunite with their original pro partners following last episode's "Switch-Up Night." In a blog post, "DWTS" pro Derek Hough revealed he and his partner, Bindi Irwin, will be doing the rumba to "(I've Had) The Time of My Life" from the movie “Dirty Dancing.”

“It feels great to be back with my baby! Pun intended. Normally, we can do our own versions of these dances, but they told us they want us to reflect the original as much as possible,” Hough said, noting that the film’s iconic lift was “tough.”

"Dancing With the Stars" airs Monday nights at 8 p.m. EDT on ABC.
