EXCLUSIVE
TMZ broke the story ... Cassidy was busted for DUI in L.A. back in January -- his third DUI arrest since 2010. Cassidy pled no contest to the DUI charge Monday.
In addition to rehab, Cassidy was also sentenced to 60 months probation. He must also complete a 9-month alcohol program.
We were previously told Cassidy had enrolled in rehab last month. It's unclear how his prior stint will affect the court-ordered program.
Cassidy had originally faced up to a year in jail -- so he should consider this a victory. Even if his wife still wants to divorce him .
