Adam Lambert's short-lived facial hair has been mocked by men's fashion glossy GQ as “testosterone problems.”

The glossy roundly knocked the 29-year-old openly gay Lambert when he stepped out in April wearing a mustache and goatee at an ASCAP event. “If you wear make-up, do not grow a mustache,” the magazine opined in naming the singer's whiskers among the “best and worst” style moments of the past 12 months.

On Tuesday, the magazine's editors went further, tweeting, “Rules of Street Style: If you have testosterone problems, a mustache doesn't always help,” along with a link to its online lineup of this year's memorable style moments to cheer or jeer at.

The Gay & Lesbian Alliance Against Defamation (GLAAD) chided the fashion glossy and demanded an apology in a tweet: “@GQfashion Being gay is not a 'testosterone problem' – Apologize to @adamlambert & the gay community.”

GQ editors quickly complied.

“Re: our Lambert tweet, we were thoughtless and apologize. We shouldn't make stupid jokes about people's testosterone. As always, we learn,” the editors messaged on Twitter.
