'Home Improvement' child star arrested on DUI charges, 'Harry Potter' had a drinking problem, and Aaron and Nick Carter's sister overdosed at 25

It's been a sad week for former child stars, and reminds us of some of the serious problems fame brought to all three of the following kids. Here is the round-up.

Taran Noah Smith arrested. The youngest Home Improvement kid was arrested after police found pot in his car. In 2001, he sued his parents over the money he made as a minor, alleging they were squandering his trust fund, including a house and a boat. "My mother always used to tell me to look out for the sharks, people who were going to take my money," Smith said. "Turns out she was talking about herself." 


Daniel Radcliff was an alcoholic. The Harry Potter star admits he had a drinking problem. "I went into work still drunk, but I never drank at work … I can point to many scenes where I’m just gone. Dead behind the eyes.” Radcliff points to the pressures of all his obligations to the public as to why he turned to alcohol. "I was living in constant fear of who I’d meet, what I might have said to them, what I might have done with them, so I’d stay in my apartment for days and drink alone. I was a recluse at 20.” Radcliff also reveals how he was bullied in school for being a child star, and how hard it is to go out in public and be recognized all the time. 


Leslie Carter overdoses. The sister of pop stars Aaron and Nick Carter was featured on the reality show "House of Carters" with her siblings. She overdosed earlier this week. 


The Carter children have had a long-standing feud with their ex-manager--their mother. In 2007, 20/20 interviewed the family (for the second time). Reporter Chris Connely asked Nick and Aaron, "You know a lot of people out there are saying, guys, she sacrificed her life for these boys' careers, she gave them every opportunity. These ungrateful boys." To which Aaron replied, "But at the same time, we gave her a job for 12 years."


Aaron expressed frustration with his mother's mismanagement of his money. He believes his mother did not pay him what he earned. "She's lied so much that she has to cover a lie with a lie," he said. 


When Jane Carter asked what the price of fame was, she said, "The loss of my family." Four out of five of Jane's children were estranged from her, as well as her ex-husband. At the time of the interview, Aaron lived with his father. Ironically, Leslie Carter was the only child not to be estranged from her. Jane was her manager. "It's going to be fun this time," Jane said. 


"Leslie, my advice to you would be, don't let mom manage you," Aaron said in 2007.
