The couple's eldest child, who is now 23, was found unresponsive in her dorm room at Hamilton College in New York and hospitalised, before being arrested on drug charges after a "small quantity" of heroin and marijuana was found during a search.

At the time, the rocker insisted he had no idea his then-teenage daughter was dabbling with drugs.

"You bring her up the best you can, you surround her with hugs and kisses and know that she may eventually fall down...," the singer told The Associated Press. "I'm shocked as much as the next parent with this situation and had no idea. But then you surround them with best help and love and move on, and that's where we're at with it.

"Steph is a great kid... She was doing great. Then a sudden and steep decline."

Drug charges were later dropped against Stephanie, and now Bon Jovi and his wife of 27 years insist the drama is in the past.

In a new People magazine expose, Dorothea states, "It happens to a lot of families that you would never know... We dealt with it as a family."

Her husband adds, "It was a terrible speed bump that we got over."

And dismissing rumours suggesting problems at home led to the drug drama, the Livin' on a Prayer star says, "We couldn't get any closer."

Always the doting dad, Bon Jovi admits it's tough to leave his wife and four kids and head out on tour, adding, "I'm not a journeyman. I know some people who are applause junkies. I'm not. I go kicking and screaming. You see my fingernails in the driveway."
