Ross and Sanders met in a Century City office building this week (where numerous lawyers practice) though she is keen to work things out, reported TMZ.
Sources connected with the couple said that although Ross is "lawyered up", she doesn't not want to split from the "Snow White and the Huntsman" director.
The couple have already attended a marriage and family therapy session in a bid to save their relationship.
Recently the model and actress was spotted sans her wedding ring, though her goal is to establish why her husband cheated on her and to get some assurances that he understands that what he did was a terrible mistake.
Stewart and Sanders engaged in a brief fling while shooting "Snow White and the Huntsman". Paparazzi shots caught the pair kissing in Stewart's Mini Cooper car, as well as on the roadside in a park near the Hollywood sign.
