The 66-year-old actress has been married to the sculptor Don Gummer for over 30 years and Streep said she does not know the secret to a happy relationship but is just relieved that they have one, reported Female First.
"I feel very lucky and I don't know what I did right. I do know many, many people who are still married to the person they originally married. I know lots of long marriages. My husband himself is divorced. He divorced at 21 after being married for one year.
The couple have four children: musician Henry, actresses Mamie and Grace, and model Louisa.
