Dennis Quaid files for divorce from third wife, Kimberly Buffington-Quaid
Quaid is asking for joint custody of the couple's 4-year-old twins Thomas and Zoe and has offered to pay spousal support according to court documents.
Buffington-Quaid had previously filed for divorce in March, but the couple put that on hold to work on their marriage. She then filed for legal separation in October.
Quaid was previously married to actresses P.J. Soles and Meg Ryan.
