The "August: Osage County" star stepped out in Los Angeles over the weekend, showing off light blonde locks in a high ponytail.
In the candid snapshot, the actress looked casual in an all-black, rocking a sporty jacket, pants, clogs and dark sunnies.
This is the first time the Oscar winner has been photographed since news broke that her half sister Nancy Motes was found dead of apparent drug overdose. Roberts has not commented on the family tragedy.
While the 46-year-old never looks bad, we prefer her signature red tresses.
It looks like she will be sporting her new light 'do at the Oscars this Sunday. Check back with toofab on the big day to see all the stars on the red carpet at the Academy Awards.
