Adam Levine denies affair but admits he 'crossed the line' after model Sumner Stroh says they had a relationship and he asked to name his 3rd baby after her

• Instagram model Sumner Stroh said she had an affair with Maroon 5 frontman Adam Levine.
• Stroh shared a TikTok on Monday with screenshots of their direct messages on Instagram.

Sumner Stroh has accused Adam Levine of cheating on his wife, Victoria's Secret model Behati Prinsloo, during a year-long affair that recently ended.

Stroh is a 23-year-old influencer and model who is predominantly active on Instagram and OnlyFans. In a TikTok video shared on Monday, she said she felt "exploited" by the Maroon 5 frontman.

"I was having an affair with who is married to a Victoria's Secret model," Stroh said. "At the time, you know, I was young, I was naive, and, I mean, quite frankly I feel exploited. I wasn't in the scene like I am now. So I was definitely very easily manipulated."

She went on to show a screenshot of a conversation with Levine conducted via Instagram DM. A representative for Stroh shared a screen recording of the messages with Insider, verifying they were sent from Levine's account to Stroh's.

"It is truly unreal how fucking hot you are," Levine wrote. "Like it blows my mind."

"I mean I think the same," Stroh replied. "Seeing u in person I was like....I'm fucked."

Later in the video, Stroh shared another screenshot that apparently shows another message from Levine. The screenshot is dated June 1, 2022.

"Adam and I were seeing each other for about a year," Stroh said. "After I stopped talking to him over a period of months, this is how he came back into my life."

The message reads: "Ok serious question. I'm having another baby and if it's w boy I really wanna name it Sumner. You ok with that? DEAD serious."

Prinsloo confirmed to People magazine she is pregnant with the couple's third child in September.

Levine and Prinsloo married in 2014 and currently have two daughters together, Gio Grace, 4, and Dusty Rose, 5.

In a statement provided to TMZ on Tuesday morning, the 43-year-old musician denied that he had a relationship with Stroh — but acknowledged that he "crossed the line."

"I used poor judgment in speaking with anyone other than my wife in ANY kind of flirtatious manner. I did not have an affair, nevertheless, I crossed the line during a regrettable period of my life," he said in the statement. "In certain instances it became inappropriate. I have addressed that and taken proactive steps to remedy this with my family."

"My wife and my family is all I care about in this world," Levine continued. "To be this naive 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."

Levine also shared the statement on his Instagram story.

In a follow-up video, Stroh stood by her account and said she feels "remorseful" and "embarrassed."

She said she decided to speak publicly because one of her friends had "attempted to sell" the story to a tabloid, which reached out to Stroh for comment on Monday, alerting her to the situation.

"I only came forward because I wanted to kill whatever story the tabloid had," she said, adding that she was "under the impression" that Levine and Prinsloo had separated.

"I believed that they were keeping it quiet to avoid the negative press," she explained. "That's why I feel exploited because he knew I believed everything he said."

Stroh added: "As soon as I had realized that was not the case, I had cut things off with him. In retrospect, I wish I would have questioned things more, I wish I wasn't so naive, but, you know, being naive is not an excuse for what I did and the role I played in this."

A representative for Stroh told Insider, "The affair took place from summer of 2021 until recently," but declined to provide further comment.

A representative for Levine did not immediately return Insider's request for comment.
