With Sumner Stroh, Adam Levine acknowledges that he “crossed the line.”

The Maroon 5 frontman, 43, addressed the allegations for first time since 23-year-old Instagram influencer Sumner Stroh publicly claimed on Monday that she had an illicit relationship with the married singer last year.

In a statement shared on social media Tuesday, Levine said he wanted to ‘clear the air’ on the rumors circulating about him, which emerged just days after his supermodel wife confirmed she was expecting their third child.

‘I used poor judgment in speaking with anyone other than my wife in ANY kind of flirtatious manner,’ the pop-rock singer said.

‘I did not have an affair, nevertheless, I crossed the line during a regrettable period of my life. In certain instances it became inappropriate. I have addressed that and taken proactive steps to remedy this with my family.’

He continued: ‘My wife and my family is all I care about in this world. To be this naïve and stupid enough to risk the only thing that truly matters to me was the greatest mistake I could ever make. I will never make it again.

‘I take full responsibility. We will get through it and we will get through it together.’

The statement however, appears to contradict Stroh’s now viral TikTok video posted on Monday where she claimed that she had an ‘affair’ with Levine for ‘about a year’ and included their flirty messages that suggested the two had met in person at least once.

The bombshell revelation sparked a frenzy on social media, with critics branding her a ‘homewrecker’ and accusing the young model of deliberately choosing to get involved with a married man.

Stroh responded to the comments in a second video posted hours later where she expressed her ‘remorse’ for her actions and issued an apology to Levine’s wife.

The social media personality, who had just moved to Los Angeles at the time of their fling, also claimed that she had naively believed Levine and Prinsloo’s marriage was ‘over’ at the time.

‘The most important part that I definitely glossed over was the fact that I was under the impression that their marriage was over,’ she said in a follow-up TikTok video.

‘I believed they were keeping it quiet to avoid the negative press because, as I had said, I was new to LA so I just assumed that with celebrities of the caliber that’s just how it was.

‘And that’s why I feel exploited because he knew I believed everything he said because of my vulnerable position of being new to LA.’

Stroh’s video was a response to a comment on her original video which read: ‘It’s no secret he’s been married for a decade. The only victim here is his wife and children.’

She claimed that she had ‘no reason’ to question what Levine had told her about the state of his marriage since he  had been contacting her through his verified Instagram account.

‘I now realize that was likely a manipulation tactic of his…just hiding in plain sight,’ she added. ‘As soon as I had realized that was not the case, I cut things off with him.

‘In retrospect, I wish I would’ve questioned things more. I wish I wasn’t so naïve, but you know, being naïve is no excuse for what I did in the role I played for this.

‘Again, in no way was I trying to gain sympathy and I fully realize I’m not the victim in this. I’m not the one who is really getting hurt here, it’s Behati and her children. And for that I am so, so, sorry.’

Stroh reiterated that she chose to come forward only after learning one of her friends had allegedly gone to the press with her claims, and she ‘wanted to kill whatever story the tabloid had.’

‘I initially wanted to go in and talk about how remorseful I feel and talk about how embarrassed and disgusted I am with myself. But I didn’t want people to look at it and think she’s playing the victim,’ she said.

‘Something I now realize I didn’t touch on enough was the fact that one of my friends had attempted to sell it. I realized yesterday when they reached out for comment, which is why I was so frantic.’

Hours earlier, Stroh had set off a social media firestorm after taking to TikTok to reveal details of her alleged illicit relationship with Levine for the first time.

The model, who is now based in Los Angeles after studying at the University of Texas, shared screenshots of their flirty exchanges on Instagram, including one bizarre message where Levine asked if he could name his new baby after her.

‘Essentially, I was having an affair with a man who is married to a Victoria’s Secret supermodel,’ she said, referring to Levine’s wife Behati, 34, who is now pregnant with the couple’s third child.

‘At the time, I was young and naïve. And I mean, quite frankly, I feel exploited. I wasn’t in the scene like I am now, so I was definitely easily manipulated.’

Stroh, who did not disclose specifics about their encounters, pointed to one Instagram DM between the pair, in which Levine writes: ‘It is unreal how f***ing hot you are. Like it blows my mind.’

‘You are 50 times hotter in person,’ he adds.

According to Stroh, who has over 338,000 followers on Instagram, she and Levine were ‘seeing each other for about a year’, until the two lost contact ‘over a period of months.’

However, the 43-year-old musician would later get back in touch in June this year to share the news that he was expecting another child with his wife of eight years, she claimed.

And to her astonishment, the heavily tattooed singer asked if he could name the child Sumner if it turned out to be a boy – a request that Stroh said left her horrified.

‘Ok serious question. I’m having another baby and if it’s [a] boy I really wanna name it Sumner. You ok with that? DEAD serious,’ Levine said, according to a screenshot of the conversation.

Stroh said she felt like she was ‘in hell,’ upon reading the odd message.

‘I mean my morals were unknowingly compromised. I was completely manipulated,’ she said in the TikTok video that has now gone viral.

She explained that she never planned on addressing the situation in such a public manner and was aware of the consequences of being ‘tied to a story like this.’

Stroh said it was only after her friend whom she had confided in about the affair, and to whom she had sent the screenshots, threatened to take her story public – that was she left determined to tell her story herself.

‘I wanted to handle this privately. I never wanted to come forward because obviously I know the implications that come with doing what I do, making money the way I do, and being an Instagram model,’ she added.

‘I had sent some screenshots recklessly to a few friends I thought I trusted and one of them had attempted to sell to a tabloid…So here I am.’

Stroh did not provide an exact timeline of the affair, however, the allegations have emerged just five days after Prinsloo confirmed her pregnancy on an Instagram post amid heavy speculation.

Earlier this month, Prinsloo and Levine were snapped having lunch together in Santa Barbara, where the soon-to-be mother-of-three had her burgeoning baby bump on full display.

She is believed to have already been expecting in July, when the couple celebrated were seen celebrating their eighth wedding anniversary during a trip to Maui, Hawaii.

Levine, however, was nowhere to be seen in the photos, while Prinsloo was photographed glum-faced and alone on the beach.

Levine was once almost as famous for his string of model girlfriends as he is for his music and sex appeal before tying the knot with Prinsloo in 2014.

Until he married Prinsloo in a romantic ceremony in Cabo San Lucas in July 2014, Levine had been the ultimate playboy with a dating career that included Victoria’s Secret models Anne Vyalitsana and Nina Agdal, as well as a rumored fling with Jessica Simpson.

The couple now have two daughters Dusty Rose, four, and Gio Grace, three and founded tequila brand Calirosa in 2021.

Prior to Sumner’s revelations, the couple appeared to have one of the strongest marriages in showbusiness but cracks have been emerging in recent weeks.

In May, the couple sold their $51million 10-bedroom, 14-bathroom home in Pacific Palisades, California.
