Kristen Stewart's stylish post-affair tour rolls on ... and yesterday, the actress popped up in Paris looking hot!

For her entrance to the Paris Fashion Week show for Balenciaga, KStew was decked out head to toe in the fashion house's creations -- which included a yellow leather jacket, floral print pants and a pair of low boots.

Her best accessory: That smile.

And she's got a good reason for that grin -- it's been reported that she's been spending a lot of time with Robert Pattinson again, following her cheating scandal with "Snow White and the Huntsman" director Rupert Sanders.

Check out more fashionable photos above, plus shots of Salma Hayek, who also enjoyed the show.
