Kristen Stewart—BACK to living with Rob and BACK to rolling through airports looking like a slob

Hey, give the girl a break…it’s not like she’s the face of the glamorous Balenciaga perfume or anything!

Kristen Stewart seen here arriving in Paris where she’ll make an appearance at the Balenciaga perfume show tomorrow was not only donning her classic laissez-fair fashion— t-shirt, jeans and a hoodie; this time she kicked it up a notch and the t-shirt even contained an unsightly stain. Hey, maybe the plane hit some turbulence!

Kristen’s messier than usual demeanor may be the lingering affect of her cheating. Yes, she and Rob Pattinson “are living together and have reconciled” explained a source, but things still aren’t the same in their relationship. Rob has been said to resemble a emotionally bruised peach. Us Weekly reveals that our British hottie “is extra-sensitive right now. He’s insecure.” (As he should.)

For more on Rob and Kristen’s “dramatic” reconciliation—including how Rob feels about moving back in with a cheating vampire—pick up the new issue of Us Weekly, on stands Friday.
