Slept on your fashion news this week? No worries. We've got you covered. All you need to know, below.

-After making her supremely elegant debut on the cover of Vogue, Rihanna switched things up and went trashy for the front of Rolling Stone, where she donned barely there cut-off shorts. [StyleList]

-On the classier end of things, Reese Witherspoon got married and wore bridal designer Monique Lhuillier. Here's some insight into why Reese and other celebs love her. [StyleList]

-Engaged songstress Lily Allen debuted sketches from her upcoming Lucy in Disguise collection, which will be vintage-inspired and dress-heavy. [StyleList]

-Meanwhile, Zoe's former assistant Brad Goreski is getting his own show on Bravo, dubbed "It's a Brad, Brad World". [StyleList]

-Britney Spears was hit with a $10 million lawsuit after a perfume deal with Brand Sense Partner, LLC. supposedly went bad. [StyleList]

-Marc Jacobs exec Robert Duffy is also in legal hot water for allegedly forcing an employee of the company to pole dance for him. Um, okay. [New York Post]

-Street style photographer The Sartorialist also took a hit this week when he described a seemingly normal-looking subject as curvy, much to the dismay of his commenters. [The Cut]

-And another famed blogger, 14-year-old Tavi Gevinson, shook the blogosphere when she explained that she'll be focusing less on fashion and more, most likely, on feminism and the like. Of course, she'll also keep busy with helping to launch a Sassy 2.0-type of magazine with uber editor Jane Pratt. Yanno, typical teenage stuff. [Style Rookie]
