So what exactly led Eric Roberts—aka Julia's older brother and Emma's dad—to shack up with such famous folks as Jeremy London, Janice Dickinson and Leif Garrett as part of the latest installment of VH1's Celebrity Rehab With Dr. Drew?
"Eric quit drugs and alcohol in 1995," the actor's wife, Eliza Roberts (an actress and casting director), tells E! News. "He has no interest in anything, other than marijuana."
Eliza explains that her husband had previously tried prescription medications to treat anxiety, but they simply didn't agree with him, and so he turned to cannabis for a cure.
"He uses marijuana as a medication. He has a prescription," Eliza explains. "However, a dependency is a dependency and he doesn't want to be dependent on it anymore."
As for how Eric's daughter is reacting to all this, Eliza simply states that "everyone in the family is very supportive of each other and of each other being their best self and being healthy."
When the subject turns to his sis, Eliza says Julia and Eric do in fact keep in touch.
"There's a lot of love in that family. They all really care about each other."
A rep for the Runaway Train stars confirms to E! News that the actor has indeed checked into the Pasadena Recovery Center to shoot Celebrity Rehab With Dr. Drew. But downplays the severity of his addiction.
"It is NOT for any serious drug/substance, or prescription drug abuse problem," reads the statement. "Eric wishes to express his genuine thanks for the concern for his well being, and appreciates the support of his family, friends and fans."
