Which onscreen co-stars are being pitted against each other in real life by two top fashion mags? Blake Lively and Leighton Meester may play BFFs onscreen, but off-screen, they're being courted by two fashion industry rivals. Anna Wintour has been chumming it up with Lively for some time; she not only graced the cover of Vogue last month but was Wintour's special guest at this year's CFDA/Vogue Fashion Fund awards dinner. And now, it seems Elle wants its own GG-approved muse; editor Roberta Myers and creative director Joe Zee showed up at Proenza Schouler high-profile presentation Wednesday with Meester in tow. Although Lively was rumored to be Vogue's special guest at the show—which meant she would be sitting opposite Meester and Team Elle—she was a no show. Has Wintour moved on, or was Lively merely trying avoid a potential catwalk cat fight? We'll let you be the judge. Xoxo.
