Actor Robert Downey Jr is reportedly proud of son's decision of voluntarily checking into rehab.
The 49-year-old 'Iron Man' star's son Indio, 20, was arrested last month for possession of cocaine in West Hollywood after police caught him smoking something out of a pipe in a car, reported Contactmusic.
"Robert clearly understands the struggle, and while of course this relapse was very upsetting to him, he is very proud of his son. Indio truly wants to stay clean. And no matter what, his dad will be right there with him ", a source said.
Indio, whose mother is Robert's ex-wife Deborah Falconer, has reportedly been in and out of rehab for many years, but has managed to stay clean until recently.
