Co-signer bankruptcy question?

I bought a 2005 Mustang last year. During college, I messed my credit up a little, so I had my fiancee co-sign on the car for me. It helped me get the car. However, she's had some problems and will now be surrendering her car and going bankrupt before we marry, so that we can work on her credit and get it back into shape. My question is, will this affect my car loan?
