Dennis Quaid is suffering a second round of heartache on the home front.
The 58-year-old-star's wife, Kimberly Quaid, 40, has filed for legal separation, five months after she withdrew her initial divorce petition when the couple decided to give their eight-year-marriage another chance, People reports.
"Kimberly and Dennis Quaid have decided to legally separate after 8 years of marriage. They ask that their privacy and the privacy of their family be respected during this difficult time," a rep for the actor told the mag.

She is reportedly seeking joint legal and sole physical custody of their 4-year-old twins, Thomas and Zoe.
Kimberly initially filed for divorce on March 2, citing irreconcilable differences. But two months later, she seemingly had a change of heart and withdrew the petition as the couple attempted to patch up their marriage.
They certainly appeared to give things a good shot: In July, they took a widely publicized trip to Bora Bora to celebrate their anniversary.
