Vanity Fair has landed some of the juiciest tell-all interviews of the year, from Lindsay Lohan's drug admission, to Hilary Swank's marriage revelations, to TomKat's secrets for a happy family (gag!). But the venerable mag may have just secured the mother of all cover stories: Britney Spears talking about her failed marriage to K-Fed.

The pop tart is planning to grant an explosive tell-all (and promote her new album) in an upcoming issue, reports Britian's The Sun.

"Britney has agreed to make Vanity Fair her first big statement about her new life. The interview will be very frank. She liked how they handled Jennifer's first interview after her divorce from Brad Pitt," a source tells the tab.

Expect to be wowed by an intimate glimpse into the life of the baby-dropping, Cheetos-popping panty hater.
