He may have over 10 million followers on Twitter, but putting Justin Bieber on the cover of a magazine doesn't necessarily mean it will sell more copies!

Vanity Fair's February cover featuring the 17-year-old pop singer is on its way to becoming the glossy's worst selling issue in 12 years, according to Women's Wear Daily.

Though the numbers for the February issue still haven't officially been tallied, the Audit Bureau of Circulation's Rapid Report claims it's only sold 246,000 copies.  If the numbers stay that low, the Bieber cover will be the magazine's worst-selling issue since July 1999, when Will Smith appeared on the cover to promote Wild, Wild West.  “Who knew 12-year-olds didn’t buy magazines?” joked a Vanity Fair spokeswoman.

As much as we adore the teen pop phenom, this isn't the first time he's bombed on the cover of a magazine!  His October 2010 Teen Vogue cover sold 121,054 copies, which is about 12 percent below the magazine's 2010 average, and his April 2010 cover of People only sold 961,762 copies, making it the third worst seller of the weekly that year.  Yikes!

Whether he can sell magazines or not, we still love the Biebs!
