The 82-year-old legendary actor's spouse Dina, 47, who appeared in her own reality show, 'Mrs Eastwood and Company' last year, has entered an exclusive rehab centre in Arizona, reported TMZ.
Dina has been married to the 'Gran Torino' actor-and-director, with whom she has a 16-year-old daughter Morgan, since 1996 and the family reside in Carmel-by-the-Sea, California, where Clint is a former mayor.
The couple met in 1993 when Dina, a former TV news anchor, interviewed the Hollywood star.
Clint is said to be an advocate for rehabilitation and is a sponsor for a facility in Monterey, California, which has named its youth addiction treatment scheme after him.
