The world was stunned when Twilight star Kristen admitted seeing director Rupert Sanders behind Rob's back while they filmed Snow White and the Huntsman.
Rob has reportedly booted Kristen out of their L.A. home after removal men were spotted at the property earlier this week, and now the heartbroken hunk is desperate for answers - and reportedly wants to speak to Sanders' wife Liberty Ross.
A source tells The Mirror: “He needs to know for his own peace of mind if theirs was just a fleeting moment.
"He hopes Liberty can help him find the answers he so desperately craves.
“Nothing is very clear at the moment but perhaps a meeting would lend some clarity to the situation. He needs to know the truth.”
Before the scandal erupted, model Liberty had ironically opened up about how her marriage became a struggle when their family emigrated to Hollywood.
She told You magazine: "Moving here [from London to L.A.] and starting a life all over again was a lot harder than I had anticipated. I just didn't think it would be as isolating and daunting as it turned out to be. I can honestly say that it took me five years to feel happy here.
"I would never say out loud that I am raising my children alone, but a lot of the time it has felt like that. I went from the glamour of working with Karl Lagerfeld and John Galliano to living on an isolated hilltop, with my husband gone most of the time."
