The Glee cast have become embroiled in fresh drama after Amber Riley seemed to cut ties with co-stars Dianna Agron and Darren Criss.

The actress, 39, who played Mercedes Jones on the show, has unfollowed the pair on Instagram, The Express Tribune reports.

Dianna and Darren, who starred as Quinn Fabray and Blaine Anderson, still followed former colleague Amber on the platform as of Tuesday.

The move prompted speculation that it was a reaction to Dianna, 38, and Darren’s surprise union with ‘villain’ Lea Michele, 38, despite years of behind-the-scenes cast drama.

The unexpected meet-up, which Lea shared on Instagram on Thursday, showed the trio posing backstage after seeing Darren, 38, perform in his latest Broadway play.

‘Night out with my beautiful friend from high school to see our former classmate perform on Broadway,’ she captioned the post — a clear nod to their days at Glee’s McKinley High.

Not everyone was quite so impressed, with many fans drawing attention to long-standing allegations that Lea mistreated several cast members during the show’s six-season run. 

Neither Lea nor Amber follow each other on Instagram. 

MailOnline has contacted representatives for Amber, Dianna, Darren and Lea for comment. 

In 2020, co-star Samantha Ware accused her of on-set bullying and ‘traumatic microaggressions’, prompting a wave of former castmates to speak out.

Among them was Heather Morris, who played cheerleader Brittany S. Pierce.

‘Was she unpleasant to work with? Very much so,’ Heather said at the time. ‘For Lea to treat others with the disrespect that she did for as long as she did, I believe she should be called out.’

Actor Dabier Snell and Yvette Nicole Brown also shared stories supporting the claims.

Naya Rivera, who died in 2020, also had on-set friction with Lea. 

Neither Dianna nor Darren nor Lea appeared on the list of accounts Amber follows on the platform, as of Tuesday

She wrote in her book: ‘One of the Glee writers once said that Lea and I were like two sides of the same battery and that about sums us up. 

‘We are both strong willed and compeтιтive – not just with each other but with everyone – and that’s not a good mixture…

‘We’re all stressed, yes, but we’re all working toward the same goal, so laugh it off and keep it movin’. Lea was a lot more sensitive, though, and it seemed like she blamed me for anything and everything that went wrong.’ 

In response to the backlash, Lea issued a public apology, saying she had ‘never judged others by their background or color of their skin’.

It all appears to be the latest example of a Glee ‘curse’ which has plagued the show and its cast for more than a decade. 

Cory Monteith, the series’ jock-turned-leading man Finn Hudson, was found ᴅᴇᴀᴅ due to an alcohol and heroin overdose in a H๏τel room in Vancouver in July 2013, aged 31. 

The Price Of Glee, a 2023 documentary, showed that the actor, who was engaged to Lea, had been battling with alcohol from the age of 13. 

The decision to recommence filming within months of the tragic incident was influenced heavily by his fiancee, according to the programme.

Four years later, Mark Salling, the ‘bad boy’ of Glee, was charged with possessing child pornography and pleaded guilty to downloading 25,000 Sєxual images of children. 

He hanged himself in a forest in Los Angeles in January 2018, just weeks before being sentenced. 

In June 2020, actress Naya, who played lesbian cheerleader Santana Lopez, was found ᴅᴇᴀᴅ at Lake Piru in California after she headed out on a rented pontoon boat with her four-year-old son and drowned. 

In May 2024, Jane Lynch claimed the Glee cast ‘liked each other very much’ while recalling her time portraying Sue Sylvester on the beloved Fox series between 2009 to 2015.

While the show certainly had a lot of behind-the-scenes drama and controversies, the actress, 64, insisted all the stars ‘got along’.

‘They liked each other very much. And they would go out — they would sneak out for lunch, and come back an hour late,’ she recalled.

Still, she joked that between takes on set she would ‘forget that they were singers and performers’ because ‘they were just on the phones like zombies’.

The Emmy Award winner noted that she and Matthew Morrison, who played Will Schuester, have ‘stayed friends’ since wrapping the series almost a decade ago.

‘Any scene I could do with him was just great,’ she said of their time portraying rivals on-screen.

Jane also praised Iqbal Theba, who starred as Principal Figgins, and Dot-Marie Jones, who played Sheldon Beiste.

‘Those are the people I worked with most, and I just loved,’ she recalled fondly.

The actress also noted it was ‘unbelievable’ that ‘Cory [Monteith], Mark [Salling] and Naya [Rivera]’ are ‘just gone’.
