Clint Eastwood's wife has entered rehab.

The legendary actor's spouse Dina Eastwood - who appeared in her own E! reality show, 'Mrs. Eastwood and Company' last year - has reportedly checked herself into a rehab facility to be treated for depression and anxiety.

The 47-year-old former TV news anchor has entered an exclusive rehab centre in Arizona, but she is not being treated for substance abuse, according to 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 interviewed the 82-year-old 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.

The actor recently celebrated the marriage of his daughter Alison - from his first marriage to Maggie Johnson - to sculptor Stacy Poitras last month.

The 40-year-old actress-and-director wed her long-time boyfriend at Saddlepeak Lodge in Calabasas, California.

The happy couple said in a statement: ''We are thrilled to be surrounded by our family for this very special day and appreciate their love and support as we begin our married life together.''
