The FBI has opened an inquiry into singer-songwriter Ryan Adams's "explicit communications with an underage fan", according to the New York Times.

The news comes a day after Adams claimed that a New York Times exposé of his treatment of women was "upsettingly inaccurate".

"Some of its details are misrepresented; some are exaggerated; some are outright false," the seven-time Grammy nominee tweeted. "I would never have inappropriate interactions with someone I thought was underage. Period."

Over Twitter, Adams also acknowledged he's not perfect and he apologized to anyone he's hurt.

His ex-wife, actor Mandy Moore, is one of seven women quoted in the original New York Times article.

She described him to the paper as controlling and psychologically abusive.

In a subsequent Instagram post, Moore wrote: "Speaking your truth can be painful and triggering but it's always worth it. My heart is with all women who have suffered any sort of trauma or abuse. You are seen and heard."
