Paris Fashion Week is in full-swing and stars are rising to the occasion. So far, I've spotted...
Rihanna rocking a Balmain blazer and harem pants (along with lingerie) to the Balmain show.
Katy Perry sparkling in a Sonia Rykiel Fall 2009 shift dress at the Sonia Rykiel show.
Gwyneth Paltrow looking casual-chic in a pair of straight leg jeans (note: these may actually be "jeggings") at designer gal pal Stella McCartney's show.
Tinsley Mortimer in a fading sheath and booties at the Emanuel Ungaro show.
