Robert Downey Jr's 20-year-old son, Indio, is reportedly undergoing treatment for an addiction to prescription pills.
Indio is currently in treatment for a medication dependency problem, according to a Wednesday report from the National Enquirer.
However, his mother Deborah Falconer told the Enquirer that the problem is not bad.
"He was not addicted," she said. "He was taking one pill a day."
'Iron Man' star Robert previously battled his own addictions in the '90s.
