Anna Wintour is rumored to have cast Lady Gaga for Vogue's marquee March 2011 cover: according to the Audit Bureau of Circulations and WWD, Gaga was 2010's "runaway hit at the newsstand."

Her July 8 Rolling Stone cover was the magazine's top-selling issue of the year; her April cover for Cosmopolitan fronted that magazine's top selling issue through the end of October; her September Vanity Fair cover was the title's second best-selling issue of the year (behind Angelina Jolie's); and her January Elle cover marked the magazine's third best-seller of the year through October.

Speaking of Wintour's preferences, she may be a fan of putting Blake Lively on covers, but it sounds like Lively doesn't sell for Vogue — her June cover was the magazine's third worst-seller of the year (and her Esquire cover was that magazine's worst seller of the year). Anne Hathaway's November Vogue cover, meanwhile, was the magazine's second-worst newsstand seller.

And over at Elle, Jennifer Lopez's cover was the magazine's second-worst seller through October, while Taylor Swift's April Elle cover was the worst seller through October.
