"Dance Moms" star and ALDC coach Abby Lee Miller is reportedly jealous of her star dancer Maddie Ziegler.

In the upcoming episode of the hit Lifetime reality TV show, the 13-year-old Ziegler will make her official come back on the show after being absent due to the filming of "The Book of Henry."

According to the synopsis for "Maddie is Back," Miller will not be very happy to see Ziegler.

In fact, the controversial coach will also decide to not give Ziegler a solo dance routine for fear that her mind may still be focused in Colin Trevorrow's upcoming movie.

Additionally, it was also revealed that Miller did not watch Ziegler's appearance on "The Ellen Show" alongside Sia.

A few months ago, Sia and her muse performed "Alive" on the said talk show.

Upon finding out that Miller didn't watch Ziegler's guesting on "The Ellen Show," the moms will ask the coach if she decided not to watch because she was jealous of Ziegler.

Miller is expected to give the moms a straight answer on Tuesday night's episode of the show.

Meanwhile, "Dance Moms" season 6, episode 8 will also see an overly concerned Ashlee asking Miller again and again what her daughter Brynn Rumfallo's fate on the show will be.

Ashlee will also insinuate that Miller is not spending as much time grooming her daughter as she would do the other girls.

The last two weeks have been very difficult for Rumfallo because Miller has been watching her every performance closely.

Two weeks ago, Miller said that she wants to keep Rumfallo on the show because she was able to bring a huge win for ALDC.

However, last week was a totally different story for the young professional dancer.

In "Debbie Allen to the Rescue," Rumfallo competed against Kalani Hilliker, but the latter was the one who won.

With this, Miller decided to not make any final decisions over Rumfallo's fate.

To add to the pressure, Rumfallo was only supposed to replace Ziegler temporarily while she was filming in New York City.

Now that she's back, Miller can decide not to tap Rumfallo any longer.

"Dance Moms" season 6, episode 8 will air on Lifetime on Tuesday at 9 p.m. ET.
