Rupert Sanders and wife Liberty Ross were seen out for the first time in public on Tuesday since news broke about his affair.

The couple's marriage has been rocked by his fling with Kristen Stewart and her relationship with boyfriend Robert Pattinson has faltered as a result.

But TMZ reports that Rupert and Liberty met up at Beverly Hills eatery, Judi's Deli for a bite to eat.

It is not known if the couple intend on working on their marriage for the sake of their two children or whether the model-turned-actress has been too humiliated to forgive her husband.

While Rupert continues to wear his wedding ring, Liberty was pictured without her band on Monday.

"Rupert is willing to do absolutely anything and everything he can to save his marriage," a source told RadarOnline.

"He realises this is the worst mistake of his life, and he cannot believe he was so stupid. The thought of losing his wife and children, who he loves more than anything in the world, is killing him."
