The end of an impulsive love affair sent actor Jeremy London into a downward spiral of booze and drugs, a close friend of the troubled actor has exclusively told RadarOnline.com.
Samantha Prado, a friend and former business associate, said the Mallrats star had relapsed long before the June 10 incident in Palm Springs, California during which he claims he was kidnapped, robbed, and forced to smoke drugs.
Prado said London, while he was separated from his wife Melissa Cunningham, found a new "love" last December.
But when that affair ended, it sent him back to drinking and drugs, she revealed.
“He would describe her to me as the ‘love of his life’... he was obsessed,” Prado told RadarOnline.com.
“Then all of a sudden the relationship ended.”
In September 2009, London entered a rehabilitation center to face his drug abuse of prescription pills.
In March this year, he insisted to PEOPLE he was sober.
As RadarOnline.com broke, Brandon Adams is awaiting trial in jail for allegedly kidnapping London along a Palm Springs roadside.
London claimed several kidnappers forced him to "use illegal drugs."
Prado said she first met London -- known for his television work, including five seasons as Griffin Holbrook on the hit FOX series Party of Five -- in 2008, when she booked into a celebrity autograph convention.
“He was a very sweet and kind,” she recalled.
But Prado said it soon emerged he was battling drug demons.
“He would pop pills that he would carry around lose in his pocket,” she said.
“He would get so wasted he couldn’t get into his hotel room and he wouldn’t remember drinking bottles of Grey Goose vodka.
Prado said, “He will be very angry with me for saying all of this, but if it saves him, it’s worth it.”
