Abby Lee Miller says that Britney Spears has gone from being a “great, confident and well taught” dancer to making her “cringe” with her online dance videos.

The controversial “Dance Moms” star told the Daily Mail in an interview published Monday that Spears, 42, used to “perform like J-Lo,” doing “athletic, real dancing.”

“‘Toxic’ I mean, any of those songs, even in her video […Baby One More Time] the iconic schoolgirl outfit, coming down the hallway with the lockers. She was dancing and she could dance,” Miller reflected. “She was great. She was just great.”

However, the former reality TV star attributed Spears’ supposed waining talent to a lack of practice — and her affinity for low-rise pants.

The “Dance Moms” alum said the “Toxic” singer’s dance abilities have wained over the years.

“She was away from her dance teacher too long,” Miller, 58, said. “That’s number one … dance is a constantly evolving art form, so you have to continually stay with the trends.”

On top of that, Miller “just wants [Spears] to pull her pants up.”

“The lower your pants are, the longer your body looks and the shorter your legs look,” she explained.

“You want to be head and neck and legs. So, she keeps pushing her pants down, making her body look longer and her legs shorter. And I’m like, ‘Pull your pants up and make your legs look longer.’”

Yet the choreographer — who knew Spears’ first dance teacher, Darni Fenerty — says she is often met with backlash when she shares her opinions on Spears’ dance videos.

“I cringe and I yell at her and then the whole world hates me, and then the world of Britney comes after me like I’m psycho. How dare I,” Miller said.

In March 2021, Miller told Spears to “close [her] ribcage” after the “Gimme More” singer posted a video of herself dancing in her living room.

However, many fans deemed the choreographer “rude as hell” and slammed her for “always being negative.”

“How about mind your own business, realize that Britney is more successful than you, and that she has people rallying behind her,” one person wrote back at the time.

“Really??…Just let her dance it out,” another added.

A third pointed out that Spears was just expressing herself amid her conservatorship, which ended a few months later, “We don’t have to get all technical. She is under an intense guardianship!”

“I cringe and I yell at her and then the whole world hates me, and then the world of Britney comes after me like I’m psycho. How dare I,” Miller said of her criticism of the star.

Yet Miller apparently didn’t learn her lesson when it came to criticizing pop stars and their dance moves.

Last month, the choreographer roasted Taylor Swift’s dancing abilities on her “Leave it on the Dance Floor” podcast, calling the 12-time Grammy winner “pigeon-toed.”

Miller went as far as to say that it was probably “too late” for Swift to improve her abilities and spent too much time “slumped over that guitar” rather than dancing.

Miller has never been one to shy away from sharing her opinions — even when it comes to big stars.

“I think she does probably think she should have danced as a kid,” she added, before calling the singer’s boyfriend Travis Kelce “a natural” on the dance floor.

“Her boyfriend is a much better dancer,” she said of Kelce. “Let’s leave it at that.”

Once again, Miller was met with backlash for commenting on the “Anti-Hero” singer’s dance moves.

“Abby just admit you are jealous and get on with your life bashing someone,” one person wrote on Twitter.

“Remember dance mom Abby Lee Miller? The one who went to prison? She also had some critiques about Taylor Swift😂,” a second person joked.

“Whether or not she took dance classes as a child is something that only she would know for sure. However, her ability to perform and connect with her audience through music is undeniable,” a third argued. “Ultimately, whether or not she dances ‘perfectly’ is less important than the passion and energy she brings to her performances.”
