Robin is reportedly at a Minnesota rehab facility called Hazeldan Addiction Treatment Center. On Sunday, he posed with a Dairy Queen employee in Lindstrom, Minn., leading people to wonder if he was back in rehab.
Williams has been open about his struggles with alcohol and drug addictions in the past.
In 2006, Williams checked into a rehab center in Oregon after admitting he relapsed after 20 years of sobriety.
"For that first week you lie to yourself, and tell yourself you can stop, and then your body kicks back and says, no, stop later," he toldThe Guardian in 2010 about his relapse. "And then it took about three years, and finally you do stop. …. Most of the time you just realize you've started to do embarrassing things."
It is also being reported that Portia De Rossi secretly checked into rehab for a one-month stay in May. According to InTouch, the Arrested Development star spent 30 days at the Passages Malibu rehab facility.
