Looks like Dennis Quaid and his wife of eight years, Kimberly Buffington-Quaid, are headed towards a permanent and final split. Kimberly has reportedly filed for separation — which will lead to an official divorce — and is asking for sole custody of their 4-year-old twins, Thomas and Zoe.

“Kimberly is fed up with Dennis’ cheating and wants out of the marriage,” a source tells TMZ. “He’s not a good husband.”

Kimberly will be represented by infamous celebrity lawyer Laura Wasser, according to the report, which also claims she’s asking for spousal support and attorney’s fees.

The couple moved to California in the summer and they’re waiting for six months to pass to establish residency before filing for an actual divorce, according to the report. But this shouldn’t come as a surprise to many since their relationship has allegedly been on the rocks for awhile now — TMZ  reported that they were set to divorce in March 2012. 

However, this isn’t the only turmoil this couple has endured in recent years. In November 2007, his two twins almost died because the hospital accidentally gave them a massive overdose of the blood thinner heparin, putting them at risk of bleeding to death.

This will be Dennis’ third divorce. He was married to P.J. Soles from 1978 to 1983, and Meg Ryan from 1991 to 2001. He married Kimberly in 2004.

We’re totally sad to hear about this news.
