Maroon 5 frontman Adam Levine took to Instagram to deny rumors of an alleged affair.

"I haven't had an affair, yet I crossed a line at an unfortunate time in my life," the 43-year-old wrote on Tuesday.

"In certain cases it became inappropriate," he explained.

"It was a mistake to speak in a flirtatious tone to anyone other than my wife."

With his Instagram post, Levine responded to a Tiktok video in which a woman claimed to have had an affair with him.

Levine said he's currently trying to work things out with his wife, Behati Prinsloo.

“My wife and family are all I care about in this world.

Being naïve and stupid enough to jeopardize the only thing that really matters in my life was the biggest mistake I could ever make.”

The singer and model have been married for eight years and are expecting their third child together.
