Rebecca Gayheart’s Toxic Marriage Meltdown

Rebecca Gayheart and Eric Dane will end their marriage in court after a toxic mix of drugs, depression and cheating fears sent their train-wreck union flying off the rails!

“Their marriage has been a disaster for more than a decade,” dished a source close to the troubled couple. An insider added: “The relationship has faced its challenges, including Eric’s wandering eye over the years.”

Both Rebecca and Eric have admitted to substance abuse problems. Each has spent time in rehab. The two wed in 2004, three years after Rebecca pleaded no contest to vehicular homicide charges after she struck and killed a nine-year-old boy.

In 2009, they were embroiled in a sex scandal when a leaked video showed a woozy Eric — then at the height of his fame as Dr. McSteamy in “Grey’s Anatomy” — in a hot tub session with Rebecca and a former teen beauty queen.

Two years later, Eric sought treatment for addiction to prescription painkillers and, in 2017, the actor checked himself into rehab under a gloomy cloud of “clinical depression,” and took a break from shooting TV’s “The Last Ship.”

Rebecca cited “irreconcilable differences” in divorce papers filed on Feb. 16. The former “Beverly Hills, 90210” star is seeking spousal support and joint custody of the couple’s preteen daughters Billie and Georgia.
