Dennis Quaid is ready to end his marriage for good.
After his wife of eight years, Kimberly Buffington-Quaid, sought legal separation in October, the Vegas star filed Friday for divorce in Los Angeles Superior Court.
The actor requests joint physical and legal custody of their 4-year-old twins, Thomas and Zoe, and offers to pay spousal support, according to the petition.
This will be the third divorce for Quaid, 58, who was previously married to Meg Ryan and P.J. Soles.
Kimberly, a former real estate agent, initially filed for divorce in March. She put the divorce on hold a month later, pulling the papers so they could work on their marriage, before then filing for separation.
