Multiple reports say DAVID CASSIDY is being divorced by his wife of his 23 years following multiple DWI busts.
Wife #3 Sue Shifrin-Cassidy is said to be is filing for divorce from the former PARTRIDGE FAMILY teen idol later today. 
Reportedly, Sue cited the “I Think I Love You” singer’s battle with alcoholism as the reason for their bust-up.
As The ENQUIRER previously reported David, 63, was arrested last month for driving while intoxicated – making three total DWIs across the nation.
His father, actor Jack Cassidy, also suffered from booze addiction and died tragically after he passed out in bed with lit cigarette and set his house ablaze.  
David’s manager of the time of his most recent arrest said that Cassidy “was doing very well in sobriety” before contentious lawsuits regarding owed Partridge Family royalties from merchandising supposedly drove him to drink. The couple have one son together, Beau, 23. 
His daughter (with model Sherry Williams), Katie Cassidy, 27, stars on the CW hit “Arrow” – ironically as a character battling substance abuse. 
David’s wife is expected to make the divorce filing official today at LA Superior Court.
