Liberty Ross hit the red carpet solo Wednesday night for the Los Angeles premiere of the gangster flick "Lawless." The model-actress's appearance marked the first time she officially has stepped out in public since intimate photographs of her 41-year-old husband Rupert Sanders embracing 22-year-old Kristen Stewart were published in Us Weekly on July 25.

The scandal was made even more savage considering that Sanders had cast Ross, 33, as Stewart's mother in "Snow White and the Huntsman."

Ross made the outing in the midst of reports that Sanders is "desperate" to keep his wife, and mother of his two children, from leaving him. TMZ reports that Ross has given the director a list of things he needs to work on before they can reconcile, including strict monogamy and being a "better husband" just generally.

On Tuesday, Ross -- who donned a casual-chic outfit of a silky green shirt and tight black leggings -- appeared to indicate exactly what state her marriage was in by what she wasn't saying. Her wedding ring was conspicuously absent from her fingers, as it has been since the cheating scandal.
