Dave Grohl is seen for the first time with ‘perfect’ porn goddess Annaliese Nielsen who ‘he began 15-year affair with’ soon after he wed as secret baby threatens his marriage

Foo Fighters rockstar Dave Grohl had a 15-year affair with a ‘perfect’ Los Angeles porn publisher and socialite, her former friends claim.

Annaliese Nielsen, 40, posted a photo of the pair together at the time, exclusively obtained by DailyMail.com from an old Instagram account.

She also shared a loving text exchange between herself and an unnamed paramour who called her ‘perfect’. 

Friends said Nielsen told them the exchange was with Grohl.

The claims emerged after Grohl admitted fathering a baby girl outside of his marriage in a stunning Instagram post last Tuesday.

The Foo Fighters frontman, 55, married Jordyn Blum in 2003 and has three daughters with her.

But after marrying, he started a romance with Nielsen, according to her friends, who claimed the secret relationship continued until at least 2019.

Nielsen’s former roommate Tyler Ammons told DailyMail.com she met Grohl at her home in the Highland Park area of Los Angeles, that she traveled with the rock star, and that Nielsen shared screenshots of their intimate and loving messages with her friends.

Nielsen acknowledged meeting Grohl, but vehemently denied the claims of an affair.

‘I haven’t spoken to Dave in years,’ she told DailyMail.com. 

‘I barely even knew him’.

There is no evidence Nielsen is the secret mother of Grohl’s new daughter.

But Ammons, 30, who lived with Nielsen in LA from 2015 to 2019, claimed he saw proof of a long-running romantic relationship between the rock star and his roommate.

‘I’ve seen plenty of text messages they shared back and forth. It was kept private but she was telling her immediate friends,’ he said.

‘The texts were like ‘I love you’. Very intimate, close things, sometimes sexual, but extremely sensual and loving. This was obviously not a one-time thing, this was an affair that had taken years.

‘One day I came home from work and they were in the living room together. They were sitting on the same couch.

‘She often talked about him, mentioning that he was going to bring her on tour with him. They’d known each other for 15 years before I came into the equation, so this had been going on a very long time.’

Claire Wilson, another former friend, said Nielsen confessed the alleged affair with Grohl within minutes of meeting her in 2019.

‘She leaned over and whispered the Dave Grohl part,’ Wilson told DailyMail.com. ‘She told me, ‘I’m his girl.’ She was very proud of it.

‘At the time I was flattered she told me a secret.’

Wilson said she later found out that it was an open secret in Nielsen’s friendship group, and she also saw text messages between Grohl and Nielsen that were shared among Nielsen’s inner circle on Facebook.

‘She talked about it so much,’ she said. ‘She did share screenshots… People openly talked about the fact that she openly talked about being his side piece.

‘It was like an inside joke within the group. People would quote the lyrics and she would laugh-react. People would say, ‘we know you’re thinking about him.’

Another former friend, Jessica Studnicky, said that she heard the rumors of the affair but didn’t believe it until Grohl was spotted at a car shop that Nielsen ran.

‘She had started out bragging about it in the girl group, about how she was Dave Grohl’s mistress,’ Studnicky said.

‘Then a couple of girls who hung around her car shop said that he would come in to see her on a regular basis and he was spotted with her there.

‘He was well known to be very unfaithful.’

Nielsen ran a softcore porn site GodsGirls from 2006 to 2020, which featured videos and photos of young, often tattooed women wearing fetish outfits.

She gained media attention in 2016 after setting up an exclusive ‘online sorority’ of women who shared intimate stories, discussed politics and compared outfits on a Facebook group called ‘Girls Night Out’.

Among the reported 2,000 members were Instagram-famous models, reality show contestants and actresses.

Nielsen was interviewed about the group on ABC’s Good Morning America in March 2016.

One 2016 story about the group published by web magazine Fusion.net described one member as ‘the quasi-famous girlfriend of a very famous singer’ – a possible allusion to Nielsen and her secret alleged affair with Grohl.

Nielsen got embroiled in a thorny controversy later in 2016 after recording a video of herself berating her Lyft cab driver over the Hawaiian hula bobblehead doll on his dashboard.

In the video, Nielsen, who is part Chinese, can be heard saying: ‘You didn’t think about, like, the pillaging of the, like, continent of Hawaii?’ adding: ‘That doll is offensive to me.’

The driver, who said he was Asian, eventually asked her to leave the vehicle and drove off after she called him ‘f**king dumba** idiot.’

Ammons said Nielsen cultivated a ‘cultish’ and toxic group of supporters around her, using her exclusive social media groups.

‘You wanted to be her friend. She made herself seem like she was god-like. A lot of us refer to those Facebook groups as a cult,’ Ammons said. 

‘They had a cult mentality. And it was like she could do no wrong. We all kind of fell for that with her.’

He said their female friends and some gay male friends were invited into Facebook groups Nielsen set up for around 50 of her inner circle, where he said she posted screenshots of her romantic conversations with Grohl.

Ammons, who now works as a construction project manager in Saint Petersburg, Florida, said at first his roommate kept the alleged affair a secret, but eventually let him in on the details.

‘When I moved in, she and her friends would be talking about it around me. I didn’t know who it was at first. I found out and asked her, and she just shook her head at me.

‘It was an unspoken thing. But we all knew it was him.

‘Either she would disappear and go hang out with him, or he would come over.

‘In a way it brought us closer because I knew that thing she was keeping to herself and close girlfriends.’

Ammons said the friendship group knew to be discreet about the relationship, because Grohl was married with kids.

‘We all knew. He’s so famous, we knew his marital status, that he had a family,’ he said.

‘They would travel with each other. I remember her going places. He offered to take her on tour. She was trying to figure out what to do with her dogs. It was in 2018.’

Foo Fighters’ Concrete and Gold Tour ran from October 14, 2017 to October 18, 2018.

Grohl’s daughter Violet, then in seventh grade, performed backing vocals at some of the concerts.

Nielsen told DailyMail.com the claims were false.

‘People are absolutely making up nonsense because they want to feel included,’ she said.

‘I have met Dave casually in passing a couple of times and he was polite and funny during our extremely brief interactions and that’s the end of anything I could say about him.’

Grohl posted on Instagram on September 10 with the shocking admission about his secret fourth child from an affair.

The statement read: ‘I’ve recently become the father of a new baby daughter, born outside of my marriage. I plan to be a loving and supportive parent to her.

‘I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness. We’re grateful for your consideration toward all the children involved, as we move forward together.’

Grohl and Blum, 48, met in 2001 and have been married since 2003, sharing three daughters – Violet, 18, Harper, 15, and Ophelia, 10.

The rock star, who has often been described as a ‘family man’ and the ‘nice guy of rock and roll’, has spoken about the importance of his family in interviews throughout the years.

In 2007, Grohl told The Guardian, Jordyn and Violet are ‘anchors that keep me from completely disappearing’.

He told Time magazine in 2012 that his family ‘changed everything that I do’.

‘When you have kids, you see life through different eyes. You feel love more deeply and are maybe a little more compassionate. It’s inevitable that that would make its way into your songwriting,’ he added.

Grohl divorced his first wife Jennifer Leigh Youngblood in 1997 after admitting to cheating.
