Fashion Week may be over, but magazine covers never cease to amaze, especially considering that red-hot singer Rihanna has returned to Vogue for a second time, gracing the front page in a feminine lace frock by Valentino for November’s Vogue cover.  Acclaimed photographer Annie Leibovitz is behind the high glamour shoot, which include the wondrous images below.  The newly pixie-cutted pop star talks to Vogue about Chris Brown, a rumored romance with Robert Pattinson, among other fabulous celebrity things.  For more mag-friendly posts, check out more from Cover Craze with Taylor Swift for Glamour & Sofia Vergara for Lucky.  Happy Styling!
