Fourth ABC staffer reveals she ALSO had an affair with TJ Holmes after Dailymail.com uncovered his affair with Amy: She claims he treated her like a 'throwaway object' as insiders say GMA was run by 'bunch of horned-up high-school students'

A fourth ABC staffer has come forward to reveal she also had an affair with former Good Morning America host T.J. Holmes - as insiders lift the lid on the sex-obsessed newsroom.

The woman, identified only as Sascha, claimed Holmes treated her as a 'throwaway object' and revealed how senior GMA executives would prey on on young, female colleagues while working long, anti-social hours.

Speaking to The Cut, sources added that women often felt pressured to have affairs with senior execs to get ahead, while HR at the company was virtually non-existent. 

One added that 'it felt like everybody was sleeping around' and claimed the GMA show was staffed by 'a bunch of horned-up high-school students'.

It comes after Dailymail.com revealed that former hosts T.J. Holmes and Amy Robach were having an affair despite both being married. Sascha said it was seeing this story go viral that made her question her own relationship with Holmes.

A fourth woman has come forward to allege she had an affair with Holmes, 45, while he was with wife Marilee Fiebig (pictured together left). Holmes also had an affair with co-anchor Robach who was married to former Melrose Place actor Andrew Shue, 55, (pictured together, right).

Since then it has emerged that Holmes - who has been described as a 'predator' - had several flings with staffers including producer Natasha Singh and former intern Jasmine Pettaway.  

Sascha claimed her affair with Holmes began when they were working together on overnight shifts in 2014. She was 27 at the time and he was 38. 

She said Holmes, now 45, had asked for her help setting up his Instagram account and became flirtatious, emailing her: 'I'm learning a lot about you. I might actually like you.' 

She revealed how the nocturnal hours of her job had left her 'exhausted and lonely' and feeling like only Holmes could empathize.

Soon after, he booked a hotel near the network’s Upper West Side headquarters and sent her the details. When she walked into the room, he was sitting on the bed, she claimed.

The pair began having sex in hotels rooms and in his locked office, which she said didn't seem out of the ordinary due to ABC's 'rampant culture of sex' - adding 'it was a pretty scandalous place.' 

She also told The Cut 'I thought I was special' and that Holmes felt like 'the only person in the building who took me seriously.'

However she eventually realized she was actually just 'part of a pattern' and he later dismissed her like a 'throwaway object.'

Their relationship fizzled after Holmes stopped working the overnight shifts to focus on his role at GMA. 

The fourth woman comes after sources allege Holmes also had an affair with Jasmine Pettaway, pictured, in 2015  when she was a 24-year-old intern

DailyMail.com previously revealed that Holmes had a three-year affair with Good Morning America producer Natasha Singh, 37, that began in 2016

Other staffers spoke to the magazine on condition of anonymity, with one saying it felt like the network only rewarded those who were 'either divas or adulterers.'

Another, identified as Ruth, said: 'It felt like everybody was sleeping around.'

She added the newsroom was staffed by 'a bunch of horned-up, high-school students' who 'learned how to do news in the 80s when people were still doing blow in the bathroom.'

Ruth claimed she raised a complaint to HR about an editor who called her 'babe' and put his hand on her thigh, but wasn't taken seriously because the company alleged she 'didn't seem that mad' about the incident.

Meanwhile Sascha alleged the network was 'more protective of the company's reputation' than the safety of female staff. 

Holmes was married to Marilee Fiebig, with whom he shares a daughter, while Robach was married to actor Andrew Shue. 

Both couples tied the knot in 2010 but have since split. Robach and Holmes, who were let go by ABC last month, remain in a relationship. He was spotted buying a gold promise ring and a chain for her 50th birthday on Monday,

Since then it has been revealed Holmes had affairs with many more women, including 24-year-old ABC intern Jasmin Pettaway in 2015.

He also embarked on a three-year fling with GMA producer Natasha Singh, who is now 37.

Since they began anchoring GMA 3 in 2020, the two hosts have always been known to have a close friendship off-screen, with both often sharing photos together from ABC's studio on Instagram

Sources allege the ABC newsroom had a rampant sex culture with women feeling pressured to have affairs with executives to secure senior positions 

Singh was married to movie producer Garrett Braren, whose credits include Crouching Tiger, Hidden Dragon: Sword of Destiny.  

Holmes has been accused of being a 'predator' particularly in his treatment towards Pettaway.

A source told Dailymail.com: 'It was Jasmin's first real job in television, and it was a big deal for her. She was looking for a mentor and she reached out to several people. T.J was someone who was responsive, but he absolutely abused the position of trust,' 

At the time Pettaway and Holmes, who had joined the ABC News Team in September 2014, were often on the same shifts.

The source added: 'Holmes was someone who would grab drinks and he and Jasmin started doing that. You must remember he was a correspondent at the time and he's taking time to speak to her about work or whatever.

'I don't know how long that had been going on before it got sexual, but I do know the first time it did was in his office, and he was about to go on air in a couple of hours.'

The source said Pettaway later told them that Holmes called her into his office where she saw he was drinking liquor.

'There's like an atmosphere shift, almost an expectation that something's going to happen, and it did.

ABC has reportedly become less scandalous since Kim Godwin took over as the network's president in 2021. 

An ABC News spokesperson told The Cut: 'We do not condone or allow harassment or intimidation of any kind and take these matters very seriously and with immediacy.'

'Creating a safe, respectful, and professional work environment for everyone has been, and continues to be, a top priority at ABC News.'

Dailymail.com has reached out to ABC for comment.

Representatives for Robach and Holmes declined to make a statement.
