Following the shocking accusations, Levine released a statement where he admitted to sending the messages to Stroh, but he denied the two ever had a sexual relationship.

"I used poor judgment in speaking with anyone other than my wife in ANY kind of flirtatious manner," the "Payphone" vocalist noted in his response. "I did not have an affair, nevertheless, I crossed the line during a regrettable period of my life."

Stroh, who is signed to the Verge Agency and graduated from the University of Texas, alleged she had previously planned to deal with their tryst privately. However, the brunette beauty explained that a friend threatened to sell the screenshots to a tabloid.

“I was under the impression that their marriage was over. I believed that they were keeping it quiet to avoid the negative press, because as I had said, I was new to L.A. So I just assumed that with celebrities of that caliber, that’s just how it was,” she explained. “As soon as I realized that was not the case, I had cut things off with him.”

The former YouTuber went on to apologize to the former Victoria's Secret model, who is currently expecting her and Levine's third child. “I’m not the one who’s really getting hurt here. It’s Behati, and her children, and for that I’m so, so sorry,” Stroh said.

An anonymous family member of Storh's backed her story and told Radar the former coach of The Voice once got Stroh front row tickets to a Maroon 5 show.

“Adam got Sumner front row tickets to his concert as well as extras for (her) mom and her friend,” the family friend told the outlet. “They hooked up the night before at his hotel. She was manipulated into thinking she wasn’t breaking up a happy marriage.”
