“Dance Moms” took a somber turn Tuesday night when coach Abby Lee Miller informed her Abby Lee Dance Company dancers in “Family Comes First” that her mother, Maryen Lorrain Miller, was in rapidly deteriorating health. “Mom is dying,” Miller revealed in the episode, an announcement that left her elite group and their mothers in tears.

Sadly, Miller’s mom passed away on Feb. 8, the same day the ALDC attended the Masters of Dance Arts in New York, which airs in next week's episode. The former dance coach died at age 86 after a months-long battle with colon cancer. Due to her mother’s passing, Miller, 47, reportedly did not attend the East Coast competition with her team.

While Season 4, episode 15, is sure to be a mournful occasion, the ALDC dancers are rumored to being paying tribute to the late dance teacher in “Lights! Camera! Dance!” According to Dance Moms Wikia, all but one member of the elite group will compete in a number titled “Amazing Grace" (similar to Maddie Ziegler’s routine of the same name shown in the Season 3 finale last September), which is rumored to be in Miller’s memory. (See a yet-to-air video of the number here.) The group’s youngest, 9-year-old Mackenzie Ziegler, will also reportedly dance a number in honor of Miller’s mother with the acrobatic solo “Little Angel.”

Another hard hit for Miller and “Dance Moms” fans: It is rumored that the group's 13-in-a-row winning streak will come to an end next week. According to the spoiler site, the group’s lyrical number only manages to place second. Mackenzie’s solo, however, is said to have scored a win for the team, placing first in her division.

Other notable numbers at the competition are rumored to include a 1950s-inspired jazz solo from 12-year-old dancer Chloe Lukasiak titled “Friday Night,” a dance which is being reported as placing fifth. Miller’s go-to lead, Maddie Ziegler, 11, was reportedly awarded with a first place win and a $750 scholarship check for her musical theater solo, “Come to the Cabaret.”

Miller confirmed her mother's death on social media Feb. 9. “You will be missed. #WeLoveYouMaryenLorrian,” Miller posted on Instagram. One day prior to her mother's passing, the Pittsburgh-based coach asked for her fans' support, saying, “Maryen Lorrain Miller is performing her last dance, please keep her in your prayers.”

According to a report from the Miami Herald, Miller was laid to rest during a private ceremony at Our Lady of Mercy Catholic Cemetery in Miami on Feb. 18.
