After a rather relatively calm Milan Fashion Week (Lea T. and a pregnant model were our highlights), Paris Fashion Week has begun with a bang (read: celebs).

We were treated to a double Kristen Stewart appearance this morning, as the star showed her face for both Balenciaga and Balmain.

Wearing a black tee, a quilted yellow jacket and printed skinny pants (natch), Stewart took in the Balenciaga show as part of her brand-repping duties. The "Twilight" star became the face of the brand's Florabotanica fragrance earlier this year and has since begun attending the Paris runway shows .

Not that she looks too happy about it. Stewart brought along her signature scowl to both shows despite the rumored good news: she and Rob Pattinson have reportedly reconciled after a brief split and are living together once again.

Smiles all around, right? Not if you're K-Stew. Even posing with Salma Hayek , Kristen kept her cool.

Check out Stewart in her Fashion Week outfit. Are you a fan of those busy pants?
